Skyworks has introduced the new Si82Ax/Bx/Cx/Dx/Ex/Fx Value and Performance Isolated Gate Drivers. Integrating a decade of customer feedback, the next-generation value and performance isolated gate driver families offer an upgrade path from the Si823x and Si823Hx ISODrivers. The entry-level Value Driver offers backward compatibility and a traditional voltage-controlled design paradigm, utilizing Skyworks' advanced, proprietary silicon isolation technology with support for 6 kV (RMS) for one-minute isolation voltage.
The Performance Driver will also offer advanced isolation technology, but in addition, it will offer a revolutionary new approach to driving power devices through its paradigm-shifting drive strength control feature called SelVCD. SelVCD provides eight selectable levels of output current for both turn on and turn off cycles, eliminating the need for gate resistors and clamping any Miller effect currents.
The device operates as a current source that maintains current output within a tight tolerance of the target across operating conditions, leading to more flexible control and enhanced switching efficiency when compared to traditional voltage-controlled drivers.
