TDA3682
The TDA3682 is a multiple output voltage regulator with power switches, intended for use in car radios with or without a microprocessor. The TDA3682 contains the following: * Four switchable regulators and one permanent active regulator (BU5V) * Two power switches with loss of ground protection * Three enable control inputs for selecting the regulators (illumination, audio, AM or FM) and the power switches (PANT and PCON); the standby mode is selected with all enable control inputs at LOW level.

FUNCTIONAL DESCRIPTION The TDA3682 is a multiple output voltage regulator with power switches, intended for use in car radios with or without a microprocessor. It contains: * Four switchable regulators and one permanent active regulator * Two power switches with loss of ground protection * Three enable control inputs EN1, EN2 and EN3. The quiescent current has a very low level of 120 A (typical value) with the regulator 2 (BU5V) active. Because of low voltage operation of the application, low dropout voltage regulators are used in the TDA3682.
Regulator 2 is always active and can not be controlled. All the other regulators and both power switches can be controlled by using pins EN1, EN2 and EN3: * Pin EN1 controls regulator 1 (illumination); see Table 1 * Pin EN2 selects regulator 3, 4 or 5 (audio, AM or FM); see Table 2 * Pin EN3 selects power switches 1 or 2 (PANT or PCON); see Table 3. Pins EN2 and EN3 are three-state level control inputs: * L means: VEN 1 V * M means: 2 V VEN 3 V * H means: VEN 4 V.

TDA3682
A backup function is present. This is realized by a switch function which acts like a sort of ideal diode between pins VP2 and STCP. The forward voltage of this ideal diode depends on the current flowing through this diode. This function makes it possible to supply regulator 2 (BU5V) when no supply voltage is present on pin VP2. A special application can be made using a backup function by connecting a capacitor between pin STCP and ground. When the supply voltage is present on pin VP2 this capacitor will be charged to a level of VP2 - 0.3 V. This charge can now be used to supply regulator 2 for a short period of time when VP2 is switched to 0 V. The delay time can be calculated using the formula: V P2 - V REG2 - 0.5 t delay = C backup x R L x ----------------------------------------------V REG2
Enable control pin EN3 POWER SWITCHES EN3 SW1 L M H off off on SW2 off on on
Example: VP2 = 14.4 V, VREG2 = 5 V, RL = 1 k and Cbackup = 100 F results in a delay time of 177 ms. When an overvoltage condition occurs, the voltage on pin STCP will be limited to approximately 18 V.
Protections All output pins are fully protected against load dump and short-circuit (foldback current protection); see Fig.3. At load dump all regulator outputs will go low, except the output of regulator 2 (BU5V). The power switches can withstand `loss of ground'. This means that the ground pin is disconnected and the switch output is connected to ground.

Multiple voltage regulator with power switches
Application information NOISE The outputs of regulators 1 to 5 are designed in such a way that the noise is very low and the stability is very good. The noise output voltage depends on output capacitor Co. Table 4 shows the influence of the output capacitor on the noise figure. Table 4 Noise figures NOISE FIGURE (V)(1) REGULATOR 1 2 3 4 5 Note 1. Measured at a bandwidth from 20 Hz to 20 kHz. STABILITY The regulators are made stable with the externally connected output capacitors. The stability can be guaranteed with almost any output capacitor. When only an electrolytic capacitor is used, the temperature behaviour of this output capacitor can cause oscillations at extreme low temperature. The following two examples show how an output capacitor value is selected. Oscillation problems can be avoided by adding a 47 nF capacitor in parallel with the electrolytic capacitor.

Example 2 (regulator 1)
Regulator 1 (illumination) is stabilized with an electrolytic capacitor of 2.2 F (ESR = 8 ). At Tamb = - 30 C the capacitor value is decreased to 0.8 F and the ESR is increased to 56 . As can be seen from Fig.9 the regulator will be stable at Tamb = -30 C. Even when only a small MKT capacitor of 47 nF is used as the output capacitor, regulator 1 will remain stable over the temperature range.

Example 1 (regulator 2)
Regulator 2 (BU5V) is stabilized with an electrolytic output capacitor of 10 F (ESR = 4 ). At Tamb = -30 C the capacitor value is decreased to 3 F and the ESR is increased to 28 . As can be seen from Fig.8 the regulator will be instable at Tamb = -30 C. Solution: To avoid problems with stability at low temperatures, the use of tantalum capacitors is recommended. Use a tantalum capacitor with a value of 10 F or an electrolytic capacitor with a higher value. Fig.9

SOLDERING Introduction to soldering through-hole mount packages This text gives a brief insight to wave, dip and manual soldering. A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). Wave soldering is the preferred method for mounting of through-hole mount IC packages on a printed-circuit board. Soldering by dipping or by solder wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joints for more than 5 seconds.
TDA3682
The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg(max)). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Manual soldering Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds.
Suitability of through-hole mount IC packages for dipping and wave soldering methods SOLDERING METHOD PACKAGE DIPPING DBS, DIP, HDIP, SDIP, SIL Note 1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. suitable suitable(1) WAVE
