Isolated gate driver SKYWORKS SI8282EC-AS featuring UL 1577 5000 VRMS isolation for safe inverter operation

Product Description

The Si828x family (Si8281/82/83/84) comprises isolated, high-current gate drivers with integrated system safety and feedback functions, ideal for driving Silicon Carbide (SiC) FETs, power MOSFETs, and IGBTs in various inverter and motor control applications. Utilizing Skyworks' proprietary silicon isolation technology, these drivers support up to 5.0 kVrms withstand voltage per UL1577, offering superior performance, reduced variation with temperature and age, tighter part-to-part matching, and enhanced common-mode rejection. The family also integrates a DC-DC controller for simplified isolated power supply implementation for the driver side. The Si828x DC-DC controller is available in two configurations: Si8281/83 with integrated power switches (limited DC-DC voltage input) and Si8282/84 with external power switches (higher voltage input). Features include user-adjustable frequency for emission minimization, soft-start for safety, and shut-down capability. The devices require minimal passive components and a miniature transformer. Input is a complementary digital input, with control and feedback signals on the isolation side. The driver side provides separate pull-up and pull-down pins, a dedicated DSAT pin for desaturation detection and controlled shutdown, and an integrated Miller clamp for strong power switch turn-off.
