1

OUT

Gate Output: Connection to gate of external MOSFET.

2

GND

Ground.

3

IN

Control Input:

MIC4414: Logic high drives the gate output above the supply voltage. Logic low forces the gate output

near ground. Do not leave floating.

MIC4415: Logic low drives the gate output above the supply voltage. Logic high forces the gate output

near ground. Do not leave floating.
