Si8239x Data Sheet
4.0 A ISODrivers with 2.5 V VDDI and Safety Features
KEY FEATURES
The Si8239x combines two isolated drivers with either an independent input control or a
single input into a single package for high power applications. All drivers operate with a Two isolated drivers in one package
2.5 V input VDD and a maximum drive supply voltage of 24 V. Up to 5 kVRMS isolation
Up to 1500 VDC peak driver-to-driver
The Si8239x isolators are ideal for driving power MOSFETs and IGBTs used in a wide
