TDA3683
Multiple voltage regulator with switch and ignition buffer
s 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:
x Low supply indication in Standby mode
x One or more switched regulators (except REG7) out of regulation
x Power switch output short-circuited to ground
x Load dump, thermal pre-warning and thermal shutdown
s Reset outputs (push-pull output stage) can be used to call a microcontroller in a
smooth way (adjustable delay) at the first power-up
s 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
s 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
s The TDA3683 has three modes of operation:
x Sleep: all outputs disabled (very low quiescent current)
x Standby: one or more standby regulators enabled (low quiescent current)
x On: all outputs enabled
s 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
s Hysteresis is incorporated on internal switching levels
s The TDA3683 is protected against Electrostatic Discharge (ESD) on all pins
s DBS23 package with low thermal resistance and flexible leads.
