POWER SUPPLY MANAGEMENT CIRCUIT; Temperature Grade: INDUSTRIAL; No. of Terminals: 16; Package Code: TSSOP; Package Shape: RECTANGULAR; Surface Mount: YES;

The ADM691A/ADM693A/ADM800L/ADM800M family of supervisory circuits offers complete single chip solutions for power supply monitoring and battery control functions in microprocessor systems. These functions include mP reset, backup-battery switchover, watchdog timer, CMOS RAM write protection, and power-failure warning. The family of products provides an upgrade for the MAX691A/93A/800M family of products. All parts are available in 16-pin DIP and SO packages. The ADM691A is also available in a space-saving TSSOP package. The following functionality is provided: Power-on reset output during power-up, power-down and brownout conditions. The circuitry remains operational with VCC as low as 1 V. Battery backup switching for CMOS RAM, CMOS micro-processor or other low power logic. A reset pulse if the optional watchdog timer has not been toggled within a specified time. A 1.25 V threshold detector for power fail warning, low battery detection, or to monitor a power supply other than +5 V.
