4A Output Current, Gate Drive, LSO5 (5-pin SOP), 8mm Creepage Distance Optocoupler

The RV1S9091A and RV1S9092A are optically coupled isolators that integrate an AlGaAs LED on the input side and a photodiode with a signal‑processing circuit and power MOSFETs on a single output‑side chip. These devices are designed for high common‑mode transient immunity (CMTI), high‑speed switching, and reliable operation at ambient temperatures up to TA = 125°C. They are suitable for driving IGBT, GaN FET, SiC FET, and Si power MOSFET gate drives.
