N/C
No connection

GND
Ground connection
3
OUT
Output current pin. Current generated due to a difference voltage
between V
SENSE+
and V
SENSE-
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 V
SENSE-
- 1.5V.
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.
5
SENSE-
This is the negative input of the current monitor and has an input
range from 20V down to 2.5V.

Operation above the absolute maximum rating may cause device failure.
Operation at the absolute maximum ratings, for extended periods, may reduce device reliability.
Notes:
1. V
