Product Overview

The XJ1801 is a highly integrated, high-performance three-phase gate driver designed for N-channel MOSFETs or IGBTs. Supporting up to 250V, it is tailored for precision motor control in compact, high-speed applications—especially unmanned aerial vehicle (UAV) electronic speed controllers (ESCs).

With integrated bootstrap capability for high-side drive and protections such as undervoltage lockout (UVLO), dead-time control, and shoot-through prevention, the XJ1801 ensures reliable and efficient operation. It is the ideal solution for drone propulsion systems requiring compact form factor, fast switching, and robust performance.
