MIC8115

MIC8115 Microprocessor Reset Circuit General Description The MIC8115 is an inexpensive microprocessor supervisory circuit that 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 /MR is forced low. 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. Datasheets and support documentation are available on Micrel’s web site at: www.micrel.com. Features Precision voltage monitor for 3.3V power supplies Specifically-tailored to the AMD Elan SC500 Series /RESET remains valid with VCC as low as 1.4V <15µA supply current 1100ms minimum reset pulse width Manual reset input Available in 4-Pin SOT-143 Package Applications Portable equipment Intelligent instrumen...
