1

VCC This is the analog supply and provides power to internal circuitry

2

GND Ground pin

3

OUT Output voltage pin.

4 VSENSE+ This is the positive input of the current monitor and has an input range from

0V up to VCC – 2V.

5 VSENSE- This is the negative input of the current monitor and has an input range

from 0V up to VCC – 2V. The current through this pin varies with differential

sense voltage.
