Mornsun make - QC962-8A is an integrated hybrid IGBT driver. Its main function is to receive the square wave signal from the controller, and convert it into an isolated, amplified gate signal which controls the IGBT’s turn-on and turn off cycle. It is a square wave signal through the optocoupler that provides reliable electrical isolation, therefore the control system cannot be affected by the common mode interference caused by IGBT.

Features:

• Built-in high CMRR opto-coupler (CMR: 30kV/µs typ., 15kV/µs min.)
• Built in bi-polar power supply
• Input signal compatible with CMOS & TTL level
• High-isolation voltage opto-coupler (3750Vrms/min)
• Short-circuit protection and output fault function
• Soft shut-down and reset timer can be used during over-current fault
• Adjustable controlled time for detecting short circuit
• Switching frequency up to 40kHz
• Drop-in replacement to M57962AL (See compatibility notes)
