ADM691A Microprocessor Supervisor with Backup Battery Switchover, Adjustable Reset and Watchdog Periods, Chip Enable Signals, 4.65V Threshold Voltage, Watchdog, Battery Backup and Low VCC Status O/Ps and 250mA Output Current
The ADM691A/ADM693A/ADM800L/ADM800M 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 family of products provides an upgrade for the MAX691A/93A/800M family of products.
All parts are available in 16-pin DIP and SO packages. The ADM691A is also available in a space-saving TSSOP package. The following functionality is provided:
Features and Benefits- Low Power Consumption:
- Precision Voltage Monitor
- ±2% Tolerance on ADM800L/M
- Reset Time Delay—200 ms, or Adjustable
- 1 µA Standby Current
- Automatic Battery Backup Power Switching
- Fast Onboard Gating of Chip Enable Signals
- Also Available in TSSOP Package (ADM691A)
