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 2.5 V input VDD and a maximum drive supply voltage of 24 V.
The Si8239x isolators are ideal for driving power MOSFETs and IGBTs used in a wide variety of switched power and motor control applications. These drivers utilize Silicon Laboratories' proprietary silicon isolation technology, supporting up to 5 kVRMS withstand voltage. This technology enables high CMTI (100 kV/µs), lower prop delays and skew, reduced variation with temperature and age and tighter part-to-part matching.
It also offers some unique features such as an output UVLO fault detection and feedback, and automatic shutdown for both drivers, an EN (active high) pin, a safe delayed start-up time of 1 ms, fail-safe drivers with default low in case of VDDI power-down, and dead time programmability. The Si8239x family offers longer service life and dramatically higher reliability compared to opto-coupled gate drivers.
