1 N/C

No connection

2 GND Ground connection

1

3 OUT Output current pin. Current generated due to a difference voltage

between VSENSE+ and VSENSE- flows out of this pin. A suitable

value resistor connected to ground creates an output voltage. The

maximum voltage out of this pin will be VSENSE- - 1.5V.

5

4 SENSE+ This pin should be connected to the rail whose current is being

measured and also provides power to internal circuitry. It is the

positive input of the current monitor and has an input range from

20V down to 2.5V. The current through this pin varies with

differential sense voltage.

4

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

range from 20V down to 2.5V.

NOTES:

(*) Mounted on 30mm x 16mm x1.1mm FR4 board with 1oz copper.

Operation above the absolute maximum rating may cause device failure.

Operation at the absolute maximum ratings, for extended periods, may reduce device reliability.

NOTES:

(‡) VSENSE is defined as the differential voltage between the SENSE+ and SENSE- pins.

VSENSE = VSENSE+ - VSENSE-
