The ADM690, ADM692 and ADM694 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 ADM691, ADM693 and ADM695 are available in 16-pin DIP and small outline packages 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.
The ADM690-ADM695 family 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.
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.
