TDA3683

Multiple voltage regulator with switch and ignition buffer

Rev. 02 — 7 October 2005

Product data sheet

1. General description

• The TDA3683 is a multiple output voltage regulator with a power switch and an

ignition buffer. Several protections and diagnostic options are incorporated in this

design.

• The TDA3683 is primarily developed to cover the complete power supply

requirements in car radio applications.

• The standby regulators (regulators 1, 2 and 3) are especially designed to supply

digital circuitry that has to be permanently connected e.g. Controller Area Network

(CAN) bus, Digital Signal Processor (DSP) core and the microcontroller. In

combination with the reset delay capacitor (pin RDC1 or pin RDC2/3) and the reset

function (pin RST1 or pin RST2/3), a proper start-up sequence for a microcontroller is

guaranteed. The storage capacitor (pin STC) makes the standby regulator outputs

insensitive for short battery drops (e.g. during engine start-up).

• The switched regulators (regulators 4, 5, 6 and 7) are intended to be used as supply

for the tuner, logic, sound processor and CD / tape control.

• The power switch (pin PSW) can be used for switching the electrically powered

antenna, display unit and CD / tape drives.

• The ignition buffer is intended to produce a clean logic output signal when a polluted

ignition key signal is used as input.

2. Features

■ Three enable pin controlled standby regulators:

◆ REG1: 5 V / 600 mA controlled by the EN1 input

◆ REG2: 3.3 V / 200 mA controlled by the EN2/3 input

◆ REG3: 1.9 V / 150 mA controlled by the EN2/3 input

■ Four mode pin controlled switched regulators:

◆ REG4: 8.5 V / 350 mA

◆ REG5: 5 V / 1.8 A

◆ REG6: 3.3 V / 1.2 A

◆ REG7: 2.4 V to 10 V / 2 A adjustable using external resistor divider

■ One mode pin controlled power switch; 2.2 A continuous and 3 A surge, with delayed

lower current limit so as to be less sensitive to inrush currents

■ One independent ignition buffer (inverted output, open-collector) with good input

protection against high transients

■ A storage capacitor is included to provide back-up supply for the standby regulators in

the event of loss of battery supply
