MIC8115
General Description
The MIC8115 is an inexpensive microprocessor supervisory
circuit that monitors power supplies in microprocessor based
systems.
The function of this device is to assert a reset if 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 V CC has risen above the designated reset
threshold level. The MIC8115 comes in a 4-pin SOT-143
package.
