Overview
The UCC27710D, produced by Texas Instruments, is a high-performance gate driver designed to drive power MOSFETs or IGBTs in various high-voltage applications. This device features both high-side and low-side gate drivers, making it suitable for offline AC-to-DC power supplies, inverters, and other high-voltage systems. The UCC27710D operates within a wide bias supply range of 10 V to 20 V and includes robust protection features such as under-voltage lockout (UVLO) and interlock functions to prevent simultaneous turn-on of both outputs.
