Dear TI experts,

Could you check the difference between the 3 parts below?

I found normal and B version in the datasheet but could not find C version.

    Hello Chase,

    The difference between these OPNs is the topology of the power-good output and the power-good delay time. The specification can be found in Table 11-1 Device Nomenclature of TPS746-Q1 datasheet.

    TPS74601PBQWDRVRQ1: open-drain power-good output with a 5-ms delay

    TPS74601PCQWDRVRQ1: push-pull power-good output with a 150-µs delay

    TPS74601PQWDRVRQ1: open-drain power-good output with a 150-µs delay

    Best,
