MIC811 Datasheet (Micrel Semiconductor) - Microprocessor Reset Circuits

MIC811, Microprocessor Reset Circuits

The MIC811 and MIC812 are inexpensive microprocessor supervisory circuits that monitor power supplies in microprocessor based systems.

The function of this device is to assert a reset if either the power supply drops below a designated reset threshold level or /MR is forced low.

Several different re
