The LTC1232CN8#PBF is a Microprocessor Supervisory Circuit provides power supply monitoring, watchdog timing and external reset for microprocessor systems. A precise internal voltage reference and comparator circuit monitors the power supply line. When an out-of-tolerance condition occurs, the reset outputs are forced to active states. The RST output is guaranteed to remain logic low even with VCC as low as 1V. The LTC1232CN8#PBF has an internal watchdog timer which forces the reset outputs to active states when the Strobe input is not forced low prior to a preset time-out period. The LTC1232CN8#PBF performs push-button reset control. The LTC1232CN8#PBF debounces the push-button input and guarantees an active reset pulse width of 250ms minimum.
