A necessary companion for discrete power MOSFETs and IGBTs as well as digital – microcontrollers, DSPs and FPGs – or analog controllers in any switched-mode power converter, STDRIVE gate drivers generate the necessary voltage and current level required to accurately and efficiently activate the power stage in industrial, consumer, computer and automotive applications.
STDRIVE comes with extensive evaluation hardware and software as well as a technical documentation toolbox to help minimize time-to-market.
The STGAP product family: The STGAP series offers isolated gate drivers with reinforced galvanic isolation and protections, ideal for driving MOSFETs, IGBTs, and SiC transistors in applications like motor control, power supplies, and EV chargers. These drivers offer superior isolation, flexible parameters, and robust diagnostics to enhance system reliability and performance. Evaluation tools and documentation are available to accelerate your time to market.
With a range spanning from single- to half-bridge and multiple-channel drivers rated for either low- or high-voltage (up to 1500 V) applications, ST also offers galvanically-isolated gate driver ICs for safety and functional requirements, System-in-Package (SiP) solutions integrating high- and low-side gate drivers and MOSFET-based power stages, responding to the industrial market trend towards higher levels of integration and lower development costs.
