ADM696ARZ Datasheet PDF - ADI

●The ADM696 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 ADM696/ADM697 is fabricated using an advanced epitaxial CMOS process combining low power consumption (5mW), extremely fast chip enable gating (5ns) and high reliability. RESET assertion is guaranteed with VCC as low as 1V. In addition, the power switching circuitry is designed for minimal voltage drop thereby permitting increased output current drive of up to 100mA without the need for an external pass transistor. The power-on reset output function during power-up, power-down and brownout conditions. The RESET voltage threshold is adjustable using an external voltage divider. The RESET output remains operational with VCC as low as 1V.

● Adjustable reset and watchdog timeout periods

● Specified over-temperature

● Adjustable low line voltage monitor

● Power ok/reset time delay

● Low switch on resistance

● Automatic battery backup switching

● Voltage monitor for power-fail or low-battery warning

● Superior upgrade for MAX696/MAX697

● 600nA Standby current

●ESD sensitive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
