LM7480-Q1: OV, SW and HGATE connection when not used

Part Number: LM7480-Q1

Dear e2e Support,

When used in an "ideal diode only" configuration, without the OVP, could you confirm that we should connect:

- OV to GND

- SW floating

- Vsns to Vbatt

- HGate floating

Regards,

    Hi,

    When LM7480-Q1 is used in  "ideal diode only" configuration, without the OVP, you can connect the pins as following,

    • If the internal disconnect switch between VSNS and SW is not used then short them together and connect to VS pin.
    • Connect OV pin to GND when OV functionality is not used.
    • HGATE can be left floating when unused.
