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 V_CC 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.
