The UCC27282QDRQ1 is an AEC-Q100 qualified 120V half-bridge gate driver from Texas Instruments, engineered to simplify high-side and low-side N-channel MOSFET drive in demanding power conversion systems. Integrating a bootstrap diode for high-side supply generation, cross-conduction (shoot-through) protection logic, and independent control inputs, this driver delivers 3A peak sink and source current capability with fast 16ns typical propagation delay, enabling efficient high-frequency switching in topologies such as synchronous buck converters, motor drive inverters, and LLC resonant power stages. With wide 4.5V to 17V supply operation, 120V HS switch-node tolerance, and -40°C to +125°C ambient performance, the device provides a compact single-chip solution for automotive 48V systems, mild-hybrid architectures, and industrial power applications requiring robust, reliable, space-efficient gate drive.
Applications
The UCC27282QDRQ1 excels in automotive 48V power systems including mild-hybrid starter-generators, traction inverters, DC-DC converters, and battery management systems requiring robust gate control. In industrial environments, the device serves motor drive controllers, servo amplifiers, robotics actuation, solar micro-inverters, telecom rectifiers, and server power supplies. Typical topologies include synchronous buck/boost converters, half-bridge and full-bridge converters, LLC resonant converters, and Class-D audio amplifiers, where the integrated bootstrap and cross-conduction protection enable efficient, reliable high-frequency operation in space-constrained, thermally challenging environments.
