The PS9552, PS9552L1, PS9552L2 and PS9552L3 are optically coupled isolators containing a GaAlAs LED on the input side and a photo diode, a signal processing circuit and a power output transistor on the output side on one chip. The PS9552 Series is designed specifically for high common mode transient immunity (CMR), high output current and high switching speed. The PS9552 Series is suitable for driving IGBTs and MOS FETs.
The PS9552, PS9552L1, PS9552L2 and PS9552L3 are optically coupled isolators designed for high common‑mode transient immunity, high output current (up to 2.5 A) and fast switching. They are intended for IGBT and power MOSFET gate‑driver applications such as industrial inverters and induction heating.
