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.
