Battery System Supervisor Preliminary Information
General Description
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 detects 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 nonmaskable 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 threshol...
