  • UCC21222: My UCC21222 drivers don't prevent simultaneous shoot through at the outputs. What can be wrong?

    Resolved
    Part Number: UCC21222 Tool/software: Each UCC21222D chip drives the half-bridge consisting of P-channel (high side) and N-channel (low side) MOSFETs. Unfortunately due to a problem in the logic, sometimes we get simultaneous positive pulses on both inputs…
