  • LM25141-Q1: LM25141-Q1

    TI Thinks Resolved
    Part Number: LM25141-Q1 We are planning to replace the existing 10 nF capacitor in the DITH pin using alternate part due to the component shortage. Can you share me what type of validation is possible to make sure the existing part and alternate part…

  • LM25141: RES pin not changing in hiccup mode

    Part Number: LM25141 Hi, I have an issue with the LM25141 in hiccup mode. I have a 22 nF capacitor on the RES pin. When overcurrent happens, after 512 cycles, the SS and Vout pin drop to 0V as expected and the drivers stop switching. However the RES…

  • LM25141-Q1: Dead time

    TI Thinks Resolved
    Part Number: LM25141-Q1 hi team, What is the minimum deadband time in your manual? The manual gives only typical and maximum values. What does this deadband time look like with temperature? Is there a curve?
