Overview
The UCC27512DRST is a single-channel, high-speed, low-side gate-driver device produced by Texas Instruments. This device is designed to effectively drive MOSFET and IGBT power switches, minimizing shoot-through current and offering rail-to-rail drive capability with extremely small propagation delays, typically 13 ns. It operates over a wide VDD range of 4.5 to 18 V and a temperature range of –40°C to 140°C, making it suitable for driving emerging wide band-gap power-switching devices such as GaN power-semiconductor devices.
