LM5060:Overcurrent power is cut off.

Part Number: LM5060

Hello,

I'm working on creating a circuit using LM5060 to control the on/off state of a battery.

However, the output is being cut off at a 14A load, and I need the circuit to support a maximum of 19A.

I'm not sure where the issue might be.

Thanks.

    Hi Jeon,

    Welcome to E2E!

    Can you increase R3 and check. These component values (Rs and Ro) has to be sized to meet the target overcurrent protection threshold (OCP). Alternatively, you can use LM5060-Q1 design calculator to check the OCP range and adjust accordingly.
