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:
Reset outputs (push-pull output stage) can be used to call a microcontroller in a
smooth way (adjustable delay) at the first power-up
Two supply pins that can withstand load dump pulses and negative supply voltages;
the second supply pin (connected to REG5 and REG6) can be supplied from a
separate external voltage (e.g. DC-to-DC downconverter) to reduce power dissipation
All regulator and power switch outputs are short-circuit proof to ground and supply
lines; the dissipation is limited in this condition since all regulators (except REG3) and
power switch have a foldback current protection incorporated
The TDA3683 has three modes of operation:
The standby regulators (including the reset function) and the ignition buffer also
function during load dump and thermal shutdown; the switched regulators and power
switch will be disabled during these conditions
Hysteresis is incorporated on internal switching levels
The TDA3683 is protected against Electrostatic Discharge (ESD) on all pins
DBS23 package with low thermal resistance and flexible leads.
Low supply indication in Standby mode
One or more switched regulators (except REG7) out of regulation
Power switch output short-circuited to ground
Load dump, thermal pre-warning and thermal shutdown
Sleep: all outputs disabled (very low quiescent current)
Standby: one or more standby regulators enabled (low quiescent current)
On: all outputs enabled
