General Description
The MIC705, MIC706, MIC707, and MIC708 are inexpensive
mircoprocessor supervisory circuit that monitors power sup-
plies in microprocessor based systems. The circuit functions
include a watchdog timer, microprocessor reset, backup
battery switchover, 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
threshold level. When the supply voltage drops below the
respective reset threshold level, /RESET is asserted.
