The ADM805 series Supervisory Circuit offers complete single chip solutions for power supply monitoring and battery control functions in microprocessor systems. These functions include µP reset, backup battery switchover, watchdog timer and power failure warning. On the ADM690A/ADM802L/ADM805L the reset voltage threshold is 4.65V. The ADM805L/M provides an active high reset output, RESET instead of RESET. The family of products is fabricated using an advanced epitaxial CMOS process combining low power consumption and high reliability. RESET assertion is guaranteed with VCC as low as 1V. They provide a pin-compatible upgrade for the MAX690A/MAX692A/MAX802L/MAX802M/MAX805L.
