Product Introduction
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 reset threshold levels are available to accommodate 3V, 3.3V, or 5V powered systems.
The MIC811 has an active-low /RESET output, while the MIC812 offers an active-high RESET output. The reset output remains asserted for a minimum of 140 ms after VCC has risen above the designed reset threshold level. Having a push-pull output stage, the MIC811/812 do not require a pull-up resistor at the output. The MIC811 and MIC812 come in a 4-lead SOT-143 package.
