Overview
MIC2753/2754 MIC2753/2754 Power Supply Supervisors Preliminary Information Micrel General Description The MIC2753 and MIC2754 are ultraminiature, full-featured, power supply supervisors featuring active-high and activelow 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 30µA.
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 (minimum) 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.
