UCC27211: does UCC27211DPRR have interlock function?

Hi

does UCC27211DPRR  have interlock function?

in datasheet,

The UCC27210 and UCC27211 features very low quiescent currents (less than 0.17 mA, refer to

the Electrical Characteristics table and contain internal logic to eliminate any shoot-through in the output driver stage

thanks.

    Hello Max,

    Thank you for supporting the UCC27211. The UCC27211 does not have the interlock to prevent LO and HO outputs from being on at the same time. There are some topologies, 2 switch forward, secondary SR, where you need the LO and HO on at the same time.

    The reference in the datasheet is referring to logic to prevent shoot thru of the internal driver output stage. The pull up driver and pull down driver has the shoot thru prevention.

    If you need a similar driver which has the input interlock, which prevents LO and HO from being on at the same time even if LI and HI are both high, the UCC27282 has this feature.

    Confirm if this addresses your question or you can post additional questions on this thread.

    Regards,
