Drive high performance across many topologies 

TI’s low-side gate drivers enable reliable and efficient power systems

Why use a low-side driver? It’s simple. A low-side gate driver will reduce your PCB space by decreasing your component count and increase your system reliability. Our low-side drivers also feature high drive current, low propagation delay, and negative voltage handling to further improve your system’s performance.

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.
