Integrated IGBT driver

Mornsun has launched the hybrid integrated IGBT driver QP12W05S-37 for high-precision and high-frequency applications.

The device is a hybrid integrated IGBT driver designed for driving IGBT modules. It 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 overcurrent protection based on de-saturation detection and output faults.

It is designed to drive high-power IGBTs and its output characteristics are also compatible with most MOS-gated power devices.

No external isolated power supply for the gate drive is required.

It is suitable to drive the modules of 600 V series IGBT (up to 600 A); 1200 V series IGBT (up to 400 A); 1700 V series IGBT (up to 200 A).

Features include: built-in high CMRR opto-coupler (CMR: typical: 30 kV/is, min:15 kV/is); single supply drive topology; built-in the isolated type DC/DC converter for gate drive; SIP package; CMOS and TTL compatible; electrical isolation voltage between input and output is 3750 VRMS (for 1 min); built-in short-circuit protection with a pin for fault output; soft turn-off time is adjustable; switching frequency up to 20 kHz.
