MORNSUN 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. • Built in high CMRR opto-coupler (CMR: Typical: 30kV/ ps, Min.:15kV/ps) • Single supply drive topology • Built in the isolated type DC/DC converter for gate drive • SIP package • CMOS&TTL compatible • Electrical isolation voltage between input and output is 3750VRMS (for 1 minute) • Built in short circuit protection circuit with a pin for fault output • Soft turn-off time is adjustable • The drive signal is ignored in the blocking time and the protection circuit reset at the end of it • Controlled time detect short circuit is adjustable • Switching frequency up to 20kHz Application • General-purpose Inverter • AC Servo Systems • Uninterruptable Power Supplies(UPS) • Welding Machines MORNSUN Science & Technology Co„Ltd.

Definition of Adjustment 1) Adjustment of soft turn-off time: (Operation of short circuit protection) When a desaturation is detected the hybrid gate driver performs a soft shutdown of the IGBT. The Soft turn-off time is 4.5pS. You can connect an Rf or Cf to adjust the Soft turn-off time. (Connecting Rf will increase the soft turn-off time and connecting Cf will decrease the soft turn-off time.) The soft turn-off time must be set 2.5pS< Tcf <10pS. Please refer to the below table. (Operation of short circuit protection) The short-circuit detection time delay is defined between the time in which...
