Micrel ETC8115
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.GENERAL DESCRIPTION
The MIC8115 has an active low /RESET output. The reset output is guaranteed to remain asserted for a minimum of 1100ms after VCC has risen above the designated reset threshold level. The MIC8115 comes in a 4-pin SOT-143 package.FEATURES
