ADM696 Microprocessor Supervisor with Backup Battery Switchover, Adjustable Low Line Voltage Monitor, Adjustable Watchdog Timer, Low Line, Power Fail and Watchdog Status Outputs and 100mA Output Current

The ADM696/ADM697 supervisory circuits offer 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 are available in 16-pin DIP and small outline packages and provide the following functions:

The ADM696/ADM697 is fabricated using an advanced epitaxial CMOS process combining low power consumption (5 mW), extremely fast Chip Enable gating (5 ns) and high reliability. RESET assertion is guaranteed with VCC as low as 1 V. In addition, the power switching circuitry is designed for minimal voltage drop thereby permitting increased output current drive of up to 100 mA without the need for an external pass transistor.
