The MIC8115 is an inexpensive microprocessor reset

circuit 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 MIC8115 has an active low RESET output. The

reset output is guaranteed to remain asserted for a

minimum of 1100ms after VCC has risen above the

designated reset threshold level. The MIC8115 comes

in a 4-pin SOT-143 package.
