Part Number: BQ77915

Hello,

this question might be stupid, but what happens when an inductive load is connected? How to protect the 2-channel mosfet from the fly-back voltage?

Thank you for answer.

  • Hi Havel,

    This app note may be useful: https://www.ti.com/lit/an/slua793/slua793.pdf It is for a similar device, the BQ77905 and has a section on FET selection that discusses transients. The recommendation is to select a FET that can handle at least double the battery voltage.

    Best regards,

    Matt
