Low-side drivers

Our low-side gate drivers enable reliable and efficient power systems

Why use our low-side driver? It’s simple. Our low-side gate drivers feature high drive current, low propagation delay, negative voltage handling, and Under-Voltage Lockout (UVLO) to maximize your system’s performance and reliability regardless of application.

Single-channel low-side gate drivers

Ideal applications include totem pole replacement, single-stage motor drive and single- leave PFC.

Dual-channel low-side gate drivers

Ideal applications include gate drive transformers, synchronous rectification, and interleaved PFC.
