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

old level. The MIC1815 comes in a 3-pin SOT-23 package.
