Multiple voltage
regulator with switch and ignition buffer
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)...
