TDA3683J

Multiple voltage regulator with switch and ignition buffer

Rev. 01 — 13 December 2004

Preliminary data sheet

1. General description

• The TDA3683J 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 TDA3683J 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. CAN bus, DPS core and the

microcontroller. In combination with the reset delay capacitor (RDC1 or RDC2/3) and

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

is guaranteed. The storage capacitor (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 (PSW) can be used for switching the electrically powered antenna,

display unit and CD / tape drives

• The ignition buffer (IGN) 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

■ A hold output (3-state) which can be used to communicate to a microcontroller in the

event of an internal or external fault condition, such as:
