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 mPreset, 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:
- Power-on reset output during power-up, power-down and brownout conditions. The RESET output remains operational with VCC as low as 1 V.
- 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.
- A 1.3 V threshold detector for power fail warning, low battery detection or to monitor a power supply other than +5 V.
The ADM8691, ADM8693 and ADM8695 are available in 16-pin DIP and small outline packages (including TSSOP) and provide three additional functions:
- Write protection of CMOS RAM or EEPROM.
- Adjustable reset and watchdog timeout periods.
- Separate watchdog timeout, backup battery switchover, and low VCC status outputs.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
