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 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
converter.
Inputs and outputs can be pulled above VDD (up to 7V
absolute maximum) without adverse effects or excessive
current draw.
Supply current is typically a low 2μA. Hysteresis is
included on all voltage detectors to prevent chattering due
to noise. The MIC2755 is available in the tiny 8-pin micro-
small-outline package.
