  • RE: UCC27712-Q1: Searching for a non-isolated half-bridge gate driver that does not have integrated diode

    Resolved
    Hello Yun, As Richard mentioned, there are several 600V half-bridge drivers that do not have the integrated diode from TI. Here are a couple of the 100V half-bridge drivers we have available at TI: UCC27288 and LM5109B-Q1. Best, Avery
