Description

The MIC1815 is an inexpensive microprocessor supervisory circuit that monitor power supplies in microprocessor based systems.

The function of MIC1815 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.
