Introduction

The FOD8333 is an advanced 2.5 A 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. The FOD8333 offers protection features necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs.

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
• 2.5 A Peak Output Current Driving Capability for Medium Power IGBT – P-Channel MOSFETs at Output Stage Enable Output Voltage Swing Close to Supply Rail (Rail-to-Rail Output) – Wide Supply Voltage Range: 5 V to 30 V
• Integrated IGBT Protection – Desaturation Detection – “Soft” IGBT Turn-Off – Automatic Fault Reset after Fixed Mute Time, Typically 33 µs – 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 Temperate Range: – -40°C to 100°C
• Safety and Regulatory Approvals – UL1577, 4,243 VRMS for 1 Minute – DIN-EN/IEC60747-5-5: 1,414 VPEAK Working Insulation Voltage Rating 8,000 VPEAK Transient Isolation Voltage Rating 8 mm Creepage and Clearance Distances
