ADM8690 Microprocessor Supervisory Circuit, 8-Pin DIP

The ADM8690–ADM8695 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 complete family provides a variety of configurations to satisfy most microprocessor system requirements.

The ADM8690, ADM8692 and ADM8694 are available in 8-pin DIP packages and provide:

The ADM8691, ADM8693 and ADM8695 are available in 16-pin DIP and small outline packages (including TSSOP) and provide three additional functions:
