TPS2121: Current limit question

Part Number: TPS2121

Hi team,

If the customer doesn't need current limit function, how should the customer do the ILM pin?

Regards,

Yoshi

    Hi Yoshi, 

    Thanks for reaching out on E2E!

    The TPS2121 should have a resistor connected to the ILM pin. If current limit is not required, you can connect an 18.7k to raise the current limit to 5.2A typical, or to a higher value.

    Thanks,

    Arthur Huang
