The ADM691A 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, CMOS RAM write protection and power-failure warning. The family of products provides an upgrade for the MAX691A/93A/800M family of products. Power-on reset output function during power-up, power-down and brownout conditions. The circuitry remains operational with VCC as low as 1V. Battery backup switching for CMOS RAM, CMOS microprocessor or other low power logic. A reset pulse if the optional watchdog timer has not been toggled within a specified time.
● Low power consumption
● Precision voltage monitor
● Automatic battery backup power switching
● Fast onboard gating of chip enable signals
● 1mA Standby current
