1 / 16 page  2022 Microchip Technology Inc. and its subsidiaries DS20006526A-page 1 MIC811/MIC812 Features • Precision Voltage Monitor for 3V, 3.3V, or 5V Power Supplies • /RESET Remains Valid with VCC as Low as 1V • 5 µA Typical Supply Current • 140 ms Minimum Reset Pulse Width Available • Manual Reset Input • Available in 4-Lead SOT-143 Package Applications • Portable Equipment • Intelligent Instruments • Critical Microprocessor Power Monitoring • Printers/Computers • Controllers General Description 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. If a microprocessor voltage supervisor with an open-drain output stage is needed, see MIC6315.
