Microchip Voltage Supervisor 3.15V max. 4-Pin SOT-143, MIC8115TUY-TR

The microchip microprocessor reset circuit MIC8115 is an inexpensive microprocessor .The supervisory circuit monitors power supplies in microprocessor-based systems. The function of the MIC8115 is to assert a reset if the power supply drops below a designated reset threshold level or if /MR is forced low. The MIC8115 has an active-low /RESET output. The reset output is guaranteed to remain asserted for a minimum of 1100 ms after VCC has risen above the designated reset threshold level.

The supply current is 15 μA
RESET remains Valid with VCC as Low as 1.4V
The minimum reset pulse width is 1100 ms
It is manual reset input
