IGBT drive optocoupler from Renesas

The PS9402 comprises a gallium aluminum arsenide (GaAlAs) led as the light emitting element and a light receiving IC. It is designed to drive igbts 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 protection circuit provides functionality such as under voltage lock out protection with hysteresis, desaturation detection and soft turn off function, fault feedback and auto reset function and an Active Miller clamp circuit. Its 16pin SOP package has 8mm outer creepage distance and 8mm air distance. Other key features inlcude output currents of 2.5A (max) and 2A (min), high speed switching (tpHL , tpLH = 200ns), 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.
