TDA3602
Information as of 2000-08-22
TDA3602; Multiple output voltage regulator
The TDA3602 is a multiple output voltage regulator, intended for use in car radios with or without a microprocessor. It contains two fixed
voltage regulators with foldback current protection (Regulators 1 and 2), and one fixed voltage regulator that also operates during load
dump and thermal shutdown. This regulator can be used to supply a microprocessor.
A back-up circuit supplies Regulator 3 during a short period after the power is cut off (negative field decay or engine start procedure). A
state control pin (pin 4) controls the device, which can be switched through four stages using the information at this pin. The switching
levels at this pin contain hysteresis.
RESET and HOLD outputs can be used to interface with a microprocessor. The RESET signal can be used to call up or initialize a
microprocessor (power-on reset). The HOLD signal can be used to control the power stages (mute signal in a low end application), or to
generate a HOLD interrupt (microprocessor application).
An internal Zener diode on the back-up pin allows this pin to withstand a load dump when supplied by the pin using a 100
series resistor.
The supply pin can withstand load dump pulses and negative supply voltages.
