UCC21759QDWQ1 – TEXAS INSTRUMENTS

The UCC21759QDWQ1 is a high-efficiency, 600V, half-bridge gate driver specifically designed for high-power applications requiring fast switching speeds and robust protection features. This device operates from a supply voltage ranging from 10V to 20V, offering a typical propagation delay of 10ns and a maximum dead time of 500ns, adjustable via external components. The integrated bootstrap diode simplifies the auxiliary power supply design. Its key feature is the integrated fault protection circuitry, including undervoltage lockout (UVLO), overcurrent protection (OCP), and short-circuit protection (SCP), enhancing system reliability. Packaged in a compact, space-saving 16-pin wide-body SOIC (WQ) package, it facilitates PCB layout._x000D_

The UCC21759QDWQ1 finds its niche in applications demanding high-voltage switching such as high-power inverters, motor drives, and uninterruptible power supplies (UPS). Its low propagation delay and high drive current capability (up to 2A peak) enable efficient operation of high-power MOSFETs or IGBTs. The integrated protection features significantly reduce the design complexity and improve the overall system robustness compared to discrete solutions. Choosing this driver offers a balance between performance, protection, and compact form factor for demanding high-voltage switching applications.
