FOD8480

Isolators - Gate Drivers Overview

The FOD8480 is a low-power optocoupler designed for isolated interface applications, specifically supporting Intelligent Power Module (IPM) digital control signal communication. It features a single channel with an isolation voltage of 5000Vrms. The device utilizes an aluminum gallium arsenide (AlGaAs) light emitting diode coupled to a photodetector. It operates within a temperature range of -40°C to +100°C and has a maximum power dissipation of 300 mW. The component is housed in a 6-pin Small Outline Integrated Circuit (SOIC) package.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation for digital control signals between controller and power stage
• Engineered for low power consumption in intelligent power module interfaces
