Package power dissipation

300mW at TA = 25°C (De-rate to zero at 150°C)

Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for

extended periods, may reduce device reliability.

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 VSENSE+ voltage. Low indicates VSENSE+ is

greater than VSENSE-

2

GND Ground pin

3

OUT Output voltage pin

4 VSENSE+ 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 VSENSE- This is the negative input of the current monitor. The current through this

pin varies with differential sense voltage
