MAX6468 Datasheet (Maxim) - Microprocessor Supervisory Reset Circuits

MAX6468, Microprocessor Supervisory Reset Circuits

The MAX6467/MAX6468 microprocessor (µP) supervisory circuits monitor single power-supply voltages from +1.8V to +5.0V and assert a reset if the supply voltage drops below its preset threshold.

An edge-triggered, one-shot manual reset function ensures that the µP enters the reset mode for a fixed tim
