QP12W05S-37 Hybrid Integrated IGBT Driver QP12W05S-37 is a hybrid integrated IGBT driver designed for driving IGBT modules. This device is a fully isolated gate drive circuit consisting of an optimally isolated gate drive amplifier and an isolated DC-to-DC converter. The gate driver provides an over-current protection function based on desaturation detection and fault output.

QP12W05S-37 / Hybrid Integrated IGBT driver-2

Definition of Characteristics 1) Operation of short circuit protection Definition of Adjustment 1) Adjustment of soft turn-off time: 2) Adjustment of short-circuit detection time delay (Operation of short circuit protection) (Operation of short circuit protection) When a desaturation is detected the hybrid gate driver performs a The short-circuit detection time delay is defined between the time in soft shutdown of the IGBT. The Soft turn-off time is 4.5μS. You can which a desaturation is detected and the time in which the gate voltage fall connect an Rf or Cf to adjust the Soft turn-off time....
