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 under
voltage detector with a power-on reset generator and reset output, an over
voltage 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 over
voltage or under
voltage thresholds. Reset outputs remain asserted for 140ms (minimum) after the input returns to normal or after releasing the manual reset. When an over
voltage condition is detected, the over
voltage output is immediately activated. Hysteresis on both thresholds prevents erratic operation due to noise.
