摘要：
1
The MIC1815 is an inexpensive microprocessor
supervisory circuit that monitor 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 accomodate 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 VCC has risen above the
designated reset threshold level. The MIC1815 comes
in a 3-pin SOT-23 package.
