MIC1815
Microprocessor Reset Circuit
General Description
The MIC1815 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
10% or 20% drop in 3.3V powered systems.
The MIC1815 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 MIC1815 comes in a 3-pin SOT-23 package.
