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 V
S+
voltage. Low indicates V
S+
is greater than V
S-
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
