MIC1810
General Description
The MIC1810 is an inexpensive microprocessor supervisory
circuit that monitors power supplies in microprocessor based
systems.
The function of these devices is to assert a reset if the power
supply drops below a designated reset threshold level. Several
different reset threshold levels are available to accommodate
5%, 10%, or 15% drop in 5V powered systems.
The MIC1810 has an active low /RESET output. The reset
output is guaranteed to remain asserted for a minimum of
100ms after V CC has risen above the designated reset thresh-
old level. The MIC1810 comes in a 3-pin SOT-23 package.
