f ceramic capacitor is connected between the ct pin and ground. when a 0.1 ? f ceramic capacitor is used, the device times out a shutdown condition if the trickle charge mode exceeds 25 minutes. the time-out timer resets at start of the constant current mode setting the time-out to 1 hour (default). when the device transitions to the constant voltage mode, the timing counter is reset and times out after an additional 2 hours if the charge current does not drop to the charge termination level for options ae, af, a g , ah, bm, bn, bo and bp. for all other options (aa, ab, ac, ad, ai, aj, ak and al), the timeout timer does not reset at every charging mode and times out in 3 hours (default). table 8 list the time-out options. table 8. watchdog timer time-out options mode timer time units trickle charge (tc) timeout reset 25 minute constant current (cc) timeout reset 1 hour constant voltage (cv) timeout reset 2 hour assuming: c ct = 0.1 ? f and v in = 5.0 v. the ct pin is driven by a constant current source and provides a linear response to increases in the timing capacitor value. thus, if the timing capacitor were to be doubled from the nominal 0.1 ? f value, the time-out periods would be doubled. the ct pin should always have a capacitor connected to ground to avoid errors in the internal timing control. the constant current provided to charge the timing capacitor is very small, and this pin is susceptible to noise and changes in capacitance value. therefore, the timing capacitor should be physically located on the printed circuit board layout as close as possible to the ct pin. since the accuracy of the internal timer is dominated by the capacitance value, a 10% tolerance or better ceramic capacitor is recommended. ceramic capacitor materials, such as x7r and x5r types are a good choice for this application. battery over-voltage protection an over-voltage event is defined as a condition where the voltage on the bat pin exceeds the maximum battery charge voltage and is set by the overvoltage protection threshold (v ovp ). if an over-voltage condition occurs, the aat3693 charge control shuts down the device until the voltage on the bat pin drops below v ovp . the aat3693 resumes normal charging operation after the overvoltage condition is removed. during an over-voltage event, the stat1 led reports a system fault. over-temperature shutdown the aat3693 has a thermal protection control circuit that shuts down charging functions if the internal die temperature exceeds the preset thermal limit threshold. once the internal die temperature falls below the thermal limit, normal operation resumes the previous charging state. battery temperature fault monitoring in the event of a battery over-temperature condition, the charge control turns off the internal pass device. the stat leds also display a system fault. after the system recovers from a temperature fault, the device resumes charging operation. the aat3693 checks battery temperature before starting the charge cycle, as well as during all phases of charging. this is accomplished by monitoring the voltage at the ts pin. this system is intended for use with negative temperature coefficient thermistors (ntc) that are typically integrated into the battery package. most of the commonly used ntc thermistors in battery packs are approximately 10 k ? at room temperature (25 c). for options ac, ad, a g , ah, ak, al, bo, and bp, the ts pin has been specifically designed to source 75 ? a of current to the thermistor. the voltage on the ts pin resulting from the resistive load should stay within a window of 331 mv to 2.39 v. if the battery becomes too hot during charging due to an internal fault or excessive constant charge current, the thermistor heats up and reduces in value, pulling the ts pin voltage lower than the ts1 threshold, and the aat3693 stops charging until the condition is removed, then charging is resumed. if the use of the ts pin function is not required by the system, it should be terminated to ground using a 10 k ? resistor. for options aa, ab, ae, af, ai, aj, bm, and bn, the internal battery temperature sensing system is comprised of two comparators which establish a voltage window for safe operation. the thresholds for the ts operating window are bounded by the ts1 and ts2 specifications. referring to table 4, the ts1 threshold = 0.30 ? v in and the ts2 threshold = 0.60 ? v in . if the use of the ts pin function is not required by the system, the ts pin should be connected to input supply v in . figure 28 shows the battery temperature sensing operation. downloaded from: http:///
