Overview
The UCC27425P is a high-speed dual MOSFET driver from Texas Instruments, designed to deliver large peak currents into capacitive loads. This device is part of the UCC2742x family, which offers three standard logic options: dual-inverting, dual-noninverting, and one-inverting and one-noninverting driver configurations. The UCC27425P specifically features one non-inverting and one inverting driver. It is available in various packages, including the PDIP-8 (P) package, SOIC-8 (D), and the thermally enhanced MSOP PowerPAD™ package (DGN).
The device is optimized for high current drive capability, with a unique BiPolar and CMOS hybrid output stage that provides high current at MOSFET Miller thresholds. It also includes enable functions for each driver, enhancing control over the operation of the driver applications. The UCC27425P is rated to operate from –40°C to 125°C, making it suitable for a wide range of applications.
