MIC1815

MIC1815 MIC1815 Microprocessor Reset Circuit Micrel General Description 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 threshold level. The MIC1815 comes in a 3-pin SOT-23 package. Features Precision voltage monitor for 10% or 20% drop in 3.3V power supplies /RESET remains valid with VCC as low as 1V 5µA supply current 100ms minimum reset pulse width No external components required Available in 3-pin SOT-23 package Applications Portable equipment Intelligent instruments Critical m...
