  • UCC27531: What is the actual quiescent current for this part?

    Resolved
    Part Number: UCC27531 Hello, I am designing the circuit where the idle current must be kept to absolute minimum. The datasheet for UCC27531DBVR does not have quiescent current, other than vague "The UCC2753x features very low quiescent currents (less than…

  • UCC27531: AC driver for inductive load

    Resolved
    Part Number: UCC27531 To my understanding, a gate driver is a type of power amplifier that accepts a low-power input from a controller IC and produces a high-current drive input for the gate of a high-power MOSFET as shown in the diagram below. Take the…
