Rutronik unveils innovative IGBT drive optocoupler

1 min read

Rutronik has announced the availability of the first intelligent IGBT drive optocoupler with integrated IGBT protection functions.

The PS9402 comprises a gallium aluminium arsenide (GaAIAs) led as the light emitting element and a light receiving IC.

The device is designed to drive IGBTs (integrated insulated gate bipolar transistors) used in inverter devices for purposes such as motor control or solar power conversion.

According to Rutronik, the PS9402 simplifies system design and contributes to greater compactness by integrating the protection circuit that previously had to be added as an external component. The integrated IGBT protection circuit is designed to provide functionality such as under voltage lock out protection with hysteresis, desaturation detection and soft turn off function. Additional functionality includes fault feedback, auto reset function and an Active Miller clamp circuit.

Its 16pin SOP package has 8mm outer creepage distance and 8mm air distance. Other features of the IGBT drive optocoupler are output currents of 2.5A (max) and 2A (min), high Speed switching (tpHL , tpLH = 200 ns), reduced supply current of 3mA (max), high common mode rejection (CMR) of 25kV/µs (min) and an extended operating temperature range of -40 to 110°C.

It conforms with the safety standards UL, CSA, DIN-EN 60747-5-2 (VDE 0884 part 2) and is compatible to ACPL-332J.
