Microprocessor Reset Circuit
The MIC1815 is an inexpensive microprocessor supervisory circuit that monitors power supplies in microprocessor based systems.
The function of these devices is to assert a reset if the power supply drops below a designated reset threshold level. Several different reset threshold levels are available to accommodate 10% or 20% drop in 3.3V powered systems.
The MIC1815 has an active low /RESET output. The reset output is guaranteed to remain asserted for a minimum of 100ms after VCChas risen above the designated reset thre.
