Semiconductors\Power Management ICs\Supervisory CircuitsSTM705/706/708/813L SupervisorsSTMicroelectronics STM705/706/708/813L Supervisors are self-contained devices which provide microprocessor supervisory functions. A precision voltage reference and comparator monitors the V CC input for an out-of-tolerance condition. When an invalid V CC condition occurs, the reset output (RST) is forced low (or high in the case of RST). These devices also offer a watchdog timer (except for STM707/708) as well as a power-fail comparator to provide the system with an early warning of impending power failure.
