Pin Name Description

1

Flag This is the current direction pin. It is open collector and allows the logic high

level to be set independent of VS+ voltage. Low indicates VS+ is greater than VS-

2

GND Ground pin

3

OUT Output voltage pin

4

S+

This is the positive input of the current monitor. It also acts as the supply

voltage pin providing current for internal circuitry. The current through this

pin varies with differential sense voltage

5

S-

This is the negative input of the current monitor. The current through this

pin varies with differential sense voltage
