LM25149-Q1: Question about Bootstrap resistor

Part Number: LM25149-Q1

Hello Team,

Thanks for your support. I got a question from customer.

Can they add bootstrap resistor in order to adjust slew rate? If yes how much is the maximum resistance of the bootstrap resistor.

  • Hi Yuta,

    Yes you can use boot resistor on LM25149-Q1. On the EVM LM25149-Q1EVM-2100 there is a 0Ω R9 you can test.

    The resistance must not be too large or the device can detect Boot UVLO. I recommend 10Ω RBOOT.

    Let me know if you have further questions.
