    Hi Prarinya, 

    Thanks for your help promoting our drivers, my name is Mamadou Diallo from the High Power Drivers' team. 

    I am not sure I understand your question, are you asking whether the input of UCC27538 are differential inputs or what specifically about the inputs of UCC27538 that customer is inquiring about?

    Can you please clarify?

    Regards,

    -Mamadou

    Hi Prarinya, 

    UCC27511A's input pins are both referenced to GND pin. This driver does NOT have a differential input type where the input pins are referenced to each other. Assuming VDD> UVLO, when an high input command is applied to the non-inverting IN+, the driver's output will go high when IN+ is at 2.2V(typ.) with respect to GND pin while IN- is also tied to GND. Similarly when in inverting configuration, the output will go High when IN- receives a signal <1.2V(typ.) with respect to GND pin while IN+ is tied to VDD.

    Please let us know if this addresses your inquiry by clicking the green button or further post on this thread.

    Thanks.

    Regards,

    -Mamadou
