MIC8114
Microprocessor Reset Circuit
General Description
The MIC8114 is an inexpensive microprocessor supervisory
circuit that monitors the power supply 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 MIC8114 has an active low /RESET output. The reset
output is guaranteed to remain asserted for a minimum
of 790ms after V
CC
has risen above the designated reset
threshold level. The MIC1814 comes in a 4-pin SOT-143
package.
Features
Precision voltage monitor for 3.3V power supplies
Specifically tailored to the
