TA8041HA
TA8041HA
Dual Voltage Regulator with Watchdog Timer
The TA8041HA is an IC specially designed for microcomputer
systems. It incorporates a highly accurate 5±0.15V
constant-voltage power supply and various system reset
functions.
The power supply section produces two outputs : main output and
sub-output. The main output can be controlled for its on / off
through the EN pin.
For system reset, it has a voltage monitoring function as well as a
watchdog timer which can self-diagnose the microcomputer
system so that program runaway can be prevented.
It also has a reverse battery protection function, a current limiter
and a thermal protection function.
Since its standby current is as small as 1mA, it can be connected
directly to an automotive battery.
