The MIC811/MIC812 are inexpensive microprocessor
supervisory circuits that monitor power supplies in
microprocessor based systems.
The function of these devices 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 VCChas risen above the designated
reset threshold level. The MIC811/MIC812 come in a 4-
pin SOT-143 package.
