LTC1232CN8#PBF

LINEAR TECHNOLOGY  LTC1232CN8#PBF  监控器电路, 高电平有效, 低电平有效复位, 4.5V-5.5V输入, DIP-8

The 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 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 LTC1232 performs push-button reset control. The LTC1232 debounces the push-button input and guarantees an active reset pulse width of 250ms minimum.
