    MIC2755
    Battery Operated Supervisor General Description Features The MIC2755 is composed of multiple comparators, a
    reset pulse generator, and logic. It is designed for
    monitoring the battery supply of portable digital systems,
    including PDAs and pagers.
    The MIC2755 can detect three different battery states:
    battery OK, low battery, and dead battery. The reset
    (/RST) output is asserted for at least 700ms when a fresh
    battery is inserted. The non-maskable interrupt output
    (/NMI) is asserted when the battery voltage is below the
    NTH threshold, indicating that high-power system
    operations should not occur. If and when battery voltage
    falls below the power-off threshold (PTH), the reset output
    is asserted and latched, inhibiting system operation until
    the battery is replaced or recharged.
    All three voltage thresholds are set using external
    resistors. A manual reset function can be implemented by
    connecting a switch directly to the power on reset/manual
    reset [RTH(/MR)] input. Internal circuitry detects switch
    activation and generates a minimum 175ms debounced
    reset signal. The MIC2755’s power supply input is
    separate from the detector inputs to allow it to be powered
    from a down-stream voltage, such as the output of a boost ...
