MIC705/706/707/708
µP Supervisory Circuit
General Description
The MIC705, MIC706, MIC707, and MIC708 are
inexpensive microprocessor supervisory circuits that
monitor power supplies in microprocessor-based systems.
The circuit functions include a watchdog timer,
microprocessor reset, power-failure warning, and a
debounced manual reset input.
The MIC705 and MIC706 offer a watchdog timer function
while the MIC707 and MIC708 have an active-high reset
output in addition to the active-low reset output.
Supply voltage monitor levels of 4.65V and 4.4V are
available. The MIC705 and MIC707 have a nominal reset
threshold level of 4.65V while the MIC706 and MIC708
have a 4.4V nominal reset threshold level. When the
supply voltage drops below the respective reset threshold
level, /RESET is asserted.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.
