The TA8007S、 TA8007F is an IC specially designed for microcomputer 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×92 and has a watchdog timer which can self-diagnose the microcomputer system so that program runaway can be prevented. It also has other monitor functions for checking the operation of the microcomputer system. Since its standby current is as small as 1.2mA (max.), it can be connected directly to an automotive battery. An output voltage of 5±0.15V is obtained for theTA8007F.
