    Docket ↓
    Supervisory Circuits
    Features Description Guaranteed Reset Assertion at VCC = 1V
    n 1.5mA Maximum Supply Current
    n Fast (35ns Max) Onboard Gating of RAM Chip Enable Signals
    n SO-8 and S16 Packaging
    n 4.65V Precision Voltage Monitor
    n Power OK/Reset Time Delay: 50ms, 200ms or Adjustable
    n Minimum External Component Count
    n 1ВµA Maximum Standby Current
    n Voltage Monitor for Power-Fail or Low Battery Warning
    n Thermal Limiting
    n Performance Specified Over Temperature
    n Superior Upgrade for MAX690 Family The LTCВ®690 family, LTC690/LTC691/LTC694/LTC695,
    provides complete power supply monitoring and battery
    control functions for microprocessor reset, battery backup, CMOS RAM write protection, power failure warning
    and watchdog timing. A precise internal voltage reference
    and comparator circuit monitor the power supply line.
    When an out-of-tolerance condition occurs, the reset
    outputs are forced to active states and the chip enable
    output unconditionally write-protects external memory. ...
