特点 Guaranteed Reset Assertion at Vcc=1V 8-Pin SOIC Plastic Package2.0mA Maximum Supply Current4.62V/4.37V Precision Voltage MonitorPower OK/Reset Time Delay: 600msMinimum External Component CountSuperior Upgrade for DS1232典型应用典型应用描述The LTC?1232 provides power supply monitoring, watchdog timing and external reset for microprocessor systems. A precise internal voltage reference and comparator circuit monitor 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 V CC as low as 1V.The LTC1232 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 watchdog timing can be set to operate on time-out periods of typically 150ms, 600ms or 1.2 seconds.The LTC1232 performs push-button reset control. The LTC1232 debounces the push-button input and guarantees an active reset pulse width of 250ms minimum.
