The MAX691ACSE+T is a single microprocessor (µP) supervisory circuit in 16 pin NSOIC package. This device is pin compatible upgrade to the MAX691 device. It improve performance with 30µA supply current, 200ms typical reset active delay on power-up and 6ns chip enable propagation delay. It include write protection of CMOS RAM or EEPROM, separate watchdog outputs, backup battery switchover and a RESET (complimentary) output that is valid with VCC down to 1V. The device is typically used in computers, controllers, intelligent instruments and critical µP power monitoring.
