FUNCTIONAL DESCRIPTION Output selection The TDA3682 is a multiple output voltage regulator with power switches, intended for use in car radios with or without a microprocessor. Regulator 2 is always active and can not be controlled. It contains: • Pin EN1 controls regulator 1 (illumination); see Table 1 All the other regulators and both power switches can be controlled by using pins EN1, EN2 and EN3: • Four switchable regulators and one permanent active regulator • Pin EN2 selects regulator 3, 4 or 5 (audio, AM or FM); see Table 2 • Two power switches with loss of ground protection • Pin EN3 selects power switches 1 or 2 (PANT or PCON); see Table 3. • Three enable control inputs EN1, EN2 and EN3. The quiescent current has a very low level of 120 µA (typical value) with the regulator 2 (BU5V) active. Pins EN2 and EN3 are three-state level control inputs: Because of low voltage operation of the application, low dropout voltage regulators are used in the TDA3682. • M means: 2 V ≤ VEN ≤ 3 V 2002 Mar 11 • L means: VEN ≤ 1 V • H means: VEN ≥ 4 V. 5 Philips Semiconductors Product specification Multiple voltage regulator with power switches Table 1 TDA3682 Enable control pin EN1 Backup function EN1 REGULATOR OUTPUT REG1 L off H on Table 2 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. Enable control pin EN2 REGULATOR OUTPUTS EN2 Table 3 REG3 REG4 REG5 L off off off M on off on H on on off The delay time can be calculated using the formula: V P2 – V REG2 – 0.5 t delay = C backup × R L × ----------------------------------------------V REG2 Enable control pin EN3 POWER SWITCHES Example: VP2 = 14.4 V, VREG2 = 5 V, RL = 1 kΩ and Cbackup = 100 µF results in a delay time of 177 ms. EN3 SW1 SW2 L off off M off on H on on 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.

Example 2 (regulator 1) 1. Measured at a bandwidth from 20 Hz to 20 kHz. Regulator 1 (illumination) is stabilized with an electrolytic capacitor of 2.2 µF (ESR = 8 Ω). At Tamb = − 30 °C the capacitor value is decreased to 0.8 µF and the ESR is increased to 56 Ω. As can be seen from Fig.9 the regulator will be stable at Tamb = −30 °C. 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. 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. MGT177 handbook, halfpage 100 Example 1 (regulator 2) ESR (Ω) Regulator 2 (BU5V) is stabilized with an electrolytic output capacitor of 10 µF (ESR = 4 Ω). At Tamb = −30 °C the capacitor value is decreased to 3 µF and the ESR is increased to 28 Ω. As can be seen from Fig.8 the regulator will be instable at Tamb = −30 °C. stable region 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 µF or an electrolytic capacitor with a higher value. 0 0.047 Fig.9 2002 Mar 11 maximum 13 0.1 1 10 100 Co (µF) Curve for selecting the value of the output capacitor for regulators 1, 3, 4 and 5.

SOLDERING Introduction to soldering through-hole mount packages 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. 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. 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. 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.

For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. 2002 Mar 11 15 Philips Semiconductors Product specification Multiple voltage regulator with power switches TDA3682 DATA SHEET STATUS DATA SHEET STATUS(1) PRODUCT STATUS(2) DEFINITIONS Objective data Development This data sheet contains data from the objective specification for product development.
