MIC8114 Micrel MIC8114
Microprocessor Reset Circuit General Description Features 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 VCC has risen above the designated reset
threshold level. The MIC1814 comes in a 4-pin SOT-143
package. Precision voltage monitor for 3.3V power supplies
Specifically tailored to the AMD Elan SC400/410
/RESET remains valid with VCC as low as 1V
