FUNCTION

Ground

Supply Voltage Input. Bypass to GND with a 0.1µF capacitor.

Power-Side Connection to the External Sense Resistor

Load-Side Connection for the External Sense Resistor

Voltage Output. VOUT is proportional to VSENSE ( VRS+ - VRS- ). Output impedance is

approximately 12kΩ.

No Connection. Not internally connected.
