TC71 : The TC70/71 is a fully-integrated power supply monitor, watchdog and battery backup circuit in a space-saving 8-pin package. When power is initially applied, the TC70/71 holds the processor in its reset state for a minimum of 500msec after VCC is in tolerance to ensure stable system start-up. After start-up, processor sanity is monitored by the on-board watchdog circuit. The processor must provide periodic highto-low level transitions to the TC70/71 to verify proper execution. Should the processor fail to supply this signal within the specified timeout period, an out-of-control processor is indicated and the TC70/71 issues a momentary processor reset as a result. The TC70 also features a wat.
