DESCRIPTION The SP2526 device is a dual +3.0V to +5.5V USB Supervisory Power Control Switch ideal for self-powered and bus-powered Universal Serial Bus (USB) applications. Each switch has low on-resistance (80m typical) and can supply 500mA minimum. The fault currents are limited to 2.0A typical and the flag output pin for each switch is available to indicate fault conditions to the USB controller. The 1ms soft start will eliminate any momentary voltage droop on the upstream port that may occur when the switch is enabled in bus-powered applications. The thermal shutdown feature will prevent damage to the device when subjected to excessive current loads. The undervoltage lockout feature will ensure that the device will remain off unless there is a valid input voltage present.

FEATURES Features of the SP2526 device include current limiting, a +2.7V undervoltage lockout, overtemperature shutdown, error flag output, soft start, a switch-on resistance of 100m over the entire supply range, and a supply current of 100A. The SP2526-1 device has an activehigh enable. The SP2526-2 device has an active-low enable. THEORY OF OPERATION The SP2526 is a dual integrated high-side power switch optimized for self-powered and buspowered Universal Serial Bus (USB) applications. There are operational conditions that will enable or disable one or more of the output MOSFET switches, depending on the type of hazard. Certain conditions will activate the open-drain error flag transistors forcing the flag outputs to ground. The SP2526 provides the following functions: 1) Independent Solid State Switches: Independent MOSFET switches connect the IN pin to the OUTA and OUTB pins when enabled by logic signals at the ENA and ENB control pins. 2) Fault Flag Conditions: Both the FLGA and FLGB pins are N-channel, open-drain MOSFET outputs capable of sinking a 10mA load to typically 100mV above ground. 3) Undervoltage Lockout: The lockout mechanism monitors the input voltage and will enable the MOSFET switches only when the voltage at the VIN pin is greater than +2.7V. 4) Current Limiting Threshold: A current limiting threshold prevents damage to the device and external load. 5) Thermal Shutdown: This mechanism protects the SP2526 and signals a fault condition if the die temperature exceeds 135OC (typical). This function has 10OC of hysteresis that prevents the MOSFET switches from turning on until the die temperature drops to 125OC (typical).
Input and Output The independent solid state MOSFET switches connect the USB +5.0V supply voltage at the IN pin to the OUTA and OUTB pins when enabled by logic signals at ENA and ENB. The IN pin is the power supply connection to the device and the drain of the output MOSFET switches. Typically, the current will flow through the switches from IN to OUTA and OUTB towards the load. If VOUT is greater than VIN when a switch is enabled, the current will flow from OUTA or OUTB to the IN pin because the MOSFET channels are bidirectional when switched on. Under normal operating condition, the MOSFET switches will present 100m maximum resistance when closed. The output MOSFETs and driver circuitry are designed to allow the MOSFET source to be externally forced to a higher voltage than the drain when the switch is off. Fault Flag Conditions Fault conditions disable one or both MOSFET switches, depending on the type of fault. FLGA and FLGB are N-channel, open-drain MOSFET outputs. The active low fault flag occurs when one of the following conditions exist: 1. Undervoltage 2. Overcurrent 3. Overtemperature Undervoltage Lockout This voltage lockout mechanism prevents the MOSFET switches from turning on until VIN is greater than +2.7V. After the switch turns on, if the voltage at VIN drops below +2.6V, the lockout circuitry shuts off both switches and signals the FLGA and FLGB fault flags. In the undervoltage lockout state, the FLGA and FLGB pins will be asserted. This detection functions only when at least one MOSFET switch is enabled. Output Current Limiting The SP2526 has a preset current-limit threshold. These switch control circuits will implement current limiting which prevents damage to the SP2526 and the external load while allowing a

minimum current of 0.5A to be delivered. The SP2526 MOSFET switches will exhibit very low resistance (<100m) or voltage drop until the current limit is reached. The fold back current is the current that is delivered into a short circuit at the output. If the SP2526 MOSFET switch is enabled into a heavy load or short-circuit, the switch will immediately go into a constant-current mode, reducing the output voltage. The respective fault flag will pull low until the condition is removed. When a heavy load is connected to the SP2526 switch output, a large transient current may flow until the current limiting circuitry responds. The SP2526 will provide a low resistance switch (100m) between the input and output pins. This low resistance will be maintained with increasing current until the 2.2A limit is reached. If load current exceeds this limit, the switch will increase its resistance. The foldback current (500mA minimum) is reached when there is a short applied to the output. The 100m switch resistance is guaranteed for all load currents, increasing or decreasing, that are below 500mA. Thermal Shutdown Under nominal load conditions, the switch resistance is very low and internal power dissipation is low. Under short circuit conditions, current is limited and internal power dissipation is higher but not extreme. Under intermediate load conditions, both the voltage across the switch and the current through the switch are at intermediate values and internal power dissipation is highest. In this last condition, the die temperature will reach the thermal limit and the switches in both channels will be shut off. As the die subsequently cools, the switch will turn on again. If the load is not removed, the device will thermal cycle in this manner to protect itself from damage. Thermal shutdown is asserted if the die temperature exceeds 135OC and will not release until the die termperature drops below 125OC. Thermal shutdown will disable both output MOSFET switches and force both FLGA and FLGB fault flags low. The delay between a current limit fault and thermal shutdown will vary with ambient temperature, board layout, and load impedance, but is typically several hundred milliseconds. A designer can command a USB controller to recognize the fault and disable the appropriate channel within this time. TYPICAL APPLICATIONS Bypass Capacitors A 0.1F to 1.0F bypass capacitor from the IN pin to the GND pin is recommended to control power supply transients. Refer to Figure 4. Without a bypass capacitor, an output short may cause sufficient ringing and damage the device. Without a bypass capacitor, excessive supply lead inductance is also a concern. Input or output transients must not exceed the absolute maximum supply voltage of VIN(MAX) = +6.0V even for a short duration to avoid risk of damage to the device. Transient Overcurrent Filter When the SP2526 is enabled, large values of capacitance at the output of the device will cause inrush current to exceed the short circuit currentlimit threshold of the device and assert a flag fault condition for FLGA and/or FLGB. The duration of this time will depend on the size of the output capacitance. During the capacitance charging time, the device enters into foldback mode. As the capacitance is charged, the current decreases below the current-limit threshold and the fault flags that are present at the FLGA and/ or FLGB pins will then be deasserted. In USB applications, it is required that output bulk capacitance is utilized to support hot-plug occurences. When the SP2526 is enabled, the flag may go active for about 1ms due to inrush current exceeding the current-limit setpoint. Additionally, during hot-plug events, inrush currents may also cause the fault flags at the FLGA and/or FLGB pins to go active. Since these conditions are not valid overcurrent faults, the USB controller must ignore the fault flags during these events. To prevent this, a 1ms RC filter can be implemented as shown in Figure 5.

tively, a 1ms debounce routine may be programmed into the USB logic controller, eliminating the need for the RC filter. Soft Start Condition The soft start feature of the SP2526 is implemented by holding the output turn-on rise time to 1ms. When off, the device has high impedance MOSFET channels that slowly become low impedance as the device powers on. This prevents an inrush current from causing voltage drops that result from charging a capacitive load and can pull the USB voltage bus below specified levels. This satisfies the USB voltage droop requirements for bus-powered applications. Refer to the circuit in Figure 6. The SP2526 can provide inrush current limiting for applications with large load capacitances where CBULK > 10F. Refer to the circuit in Figure 7 for a configuration that will meet USB transient regulation specifications with large load capacitances. Enable Input The ENA and ENB control pins must be driven to a logic high or logic low for a clearly defined signal input. Floating these control lines may cause unpredictable operation. USB Compliance The SP2526 is ideal for self-powered and buspowered Universal Serial Bus (USB) applications. A USB port provides a +5.0V bus and ground return line in addition to a twisted pair for data. The SP2526 will comply with the following USB requirements: 1) The fault current is well below the UL 25VA safety requirements; 2) The Flag Outputs are available to indicate fault conditions to USB controllers; 3) The MOSFET switches' low on-resistance meets USB voltage drop requirements;
4) Each MOSFET switch channel can supply 500mA as required by USB downstream devices; 5) Soft start eliminates any momentary voltage drops on the upstream port that may occur when the switches are enabled in bus-powered applications. Refer to Table 1 for a USB compliance summary of the SP2526. Additional features include the following: 6) An Undervoltage Lockout ensures that the device remains off unless there is a valid input supply voltage present; 7) +3.3V and +5.0V logic compatible enable inputs; 8) Thermal Shutdown prevents the possiblity of catastrophic switch failure from high-current loads; 8) The device is available in both active-high and active-low versions. Refer to Figures 8 to 26 for typical performance characteristics of the SP2526.
