Description

The LTC694CN8 is an electronic component model in the category of supervisors. It belongs to the LTC®690 family, which provides complete power supply monitoring and battery control functions for microprocessor reset, battery back-up, CMOS RAM write protection, power failure warning, and watchdog timing. It features a precise internal voltage reference and comparator circuit that monitors the power supply line. When an out-of-tolerance condition occurs, the reset outputs are forced to active states, and the chip enable output unconditionally write-protects external memory. The RESET output is guaranteed to remain logic low even with VCC as low as 1V.
