Pin Description
Pin Name Description
1 VCC This is the analogue supply and provides power to internal circuitry
2 GND Ground pin
3 OUT Output voltage pin. NMOS source follower with 20 μA bias to ground
4 SENSE+
This is the positive input of the current monitor and has an input range from 40V
(60V transient) down to 3V. 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 40V
(60V transient) down to 3V
