TA8041F

Dual Voltage Regulator with Watchdog Timer

The TA8041F 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.

Weight: 0.79 g (Typ.)
