TPS566231: Question about negative overcurrent protection

Guru 19535 points
Part Number: TPS566231
Other Parts Discussed in Thread: TPS54824

Is there detailed information or application note for Negative overcurrent protection (INOCL)?

One customer hope to confirm protection function for negative (reverse polarity) current from output side.

When TPS566231 can not protect reverse current, please let me know reference external components.

Best regards,


  • Hi Satoshi,

    Sorry we don't have specific document to introduce Negative overcurrent protection. But below description from tps54824 datasheet you can refer to.

    About 'When TPS566231 can not protect reverse current', what application you are worried about?

    TPS566231 has the NOC protection. If low-side MOSFET sinking current exceeded NOC limit (-3.4A, typ), low-side MOSFET will turn off.

    Let me know if you have further questions.
