Microchip MIC811MUY-TR, Supervisory Circuit 4.38V 4-Pin, SOT-143

The Microchip MIC811MUY-TR is an 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. The MIC811MUY-TR has an active low output. The reset output is guaranteed to remain asserted for a minimum of 140ms after VCC has risen above the designed reset threshold level. Having a push-pull output stage, the MIC811 does not require a pull-up resistor at the output. The MIC811MUY-TR comes in a 4-pin SOT-143 package.
