FOD8334 Overview
Description
The FOD8334 is an advanced 4.0 A peak output current IGBT drive optocoupler capable of driving medium-power IGBTs with ratings up to 1,200 V and 150 A. It is suited for fast-switching driving of power IGBTs and MOSFETs in motor-control inverter applications and high-performance power systems.
Key Features
- Input LED Drive Facilitates Receiving Digitally Encoded Signals from PWM Output
- Optically Isolated Fault-Sensing Feedback
- Active Miller Clamp to Shut Off IGBT During High dv/dt without Negative Supply Voltage
- High Noise Immunity Characterized by Common Mode Rejection – 35 kV/µs Minimum, VCM = 1500 VPEAK
- Integrated IGBT Protection – Desaturation Detection – “Soft” IGBT Turn-Off – Under-Voltage Lockout (UVLO) with Hysteresis
- Fast Switching Speed Over Full Operating Temperature Range – 250 ns Maximum Propagation Delay – 100 ns Maximum Pulse Width Distortion
- Extended Industrial Temperature Range: – –40°C to 100°C
