Power Supply Supervisors
Preliminary Information
General Description
The MIC2753 and MIC2754 are ultraminiature, full-featured,
power supply supervisors featuring active-high and active-
low reset outputs, respectively.
The MIC2753/4 includes an undervoltage detector with a
power-on reset generator and reset output, an overvoltage
detector with a separate output for activating crowbar circuits,
and a debounced manual reset input. Typical supply current
is a low 30
μ
A.
These devices provide a 140ms minimum reset output at
power-on and assert their reset outputs any time the input
voltage deviates beyond preset overvoltage or undervoltage
thresholds. Reset outputs remain asserted for 140ms (mini-
mum) after the input returns to normal or after releasing the
manual reset. When an overvoltage condition is detected, the
overvoltage output is immediately activated. Hysteresis on
both thresholds prevents erratic operation due to noise.
