4.0 A Symmetric Drive ISODrivers with 20 V VDDIH, Low Propagation Delay and High Transient Immunity
The Si8252x combines two isolated drivers into a single package for high power applications. These drivers can operate with a 4.5 V – 20 V input VDD and a maximum drive supply voltage of 30 V.
The Si8252x is ideal for driving power MOSFETs and IGBTs used in a wide variety of switched power and motor control applications. These drivers utilize Skyworks' proprietary silicon isolation technology, supporting up to 5 kVRMS for 1 minute isolation voltage. This technology enables high CMTI (125 kV/µs), lower prop delays and skew, reduced variation with temperature and age and tighter part-to-part matching.
The unique architecture of the output stage features a booster device that provides a higher pull up capability at the Miller plateau region of the load power switch to support faster turn-on times. This driver family also offers some unique features such as over-temperature protection, output UVLO fault detection, dead time programmability and fail-safe drivers with default low in case of loss of input side power. The Si8252x family offers longer service life and dramatically higher reliability compared to opto-coupled gate drivers.
Automotive Grade is available. These products are built using automotive specific flows at all steps in the manufacturing process to ensure the robustness and low defectivity required for automotive applications.
