REGULATOR WITH WATCHDOG TIMER
The TA8005S TA8005F is an IC specially designed for micro-computer systems. It incorporates a highly accurate constant-voltage power supply (5±0.25V) and various system reset functions. For system reset, it monitors the output voltage of VREG×85% and has a watchdog timer which can self-diagnose the microcomputer system so that program runaway can be prevented. Since its bias current is as small as 1.4mA (max.) , it can be connected directly to an automotive battery.
