MIC6315

MIC6315 Open-Drain µP Reset Circuit General Description The MIC6315 is an inexpensive reset generator circuit that monitors power supplies in microprocessor-based systems. The function of this device is to assert a reset if either the power supply drops below a designated reset threshold level or /MR is forced low. Several different reset threshold levels are available to accommodate 3V, 3.3V, or 5V powered systems. The MIC6315 has an active low, open-drain /RESET output. The reset output is guaranteed to remain asserted for a minimum of either 20ms, 140ms, or 1100ms after VCC has risen above the designed reset threshold level. The MIC6315 is available in a 4-pin SOT-143 package. Datasheets and support documentation are available on Micrel’s web site at: www.micrel.com.
