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.
