The function of MIC811/MIC812 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 accomodate 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 is guaranteed to remain asserted for a minimum of 140ms after VCC has risen above the designated reset threshold level. The MIC811/MIC812 come in a 4-pin SOT-143 package.
