Overview
The UCC27212A-Q1 is a high-performance, automotive-grade half-bridge driver designed by Texas Instruments. This device is AEC-Q100 qualified, ensuring it meets stringent automotive standards. It operates over a wide junction temperature range of –40°C to +150°C, making it suitable for various harsh environments. The UCC27212A-Q1 is based on the popular UCC27211 MOSFET drivers but offers an extended operating range down to 5V, which helps in reducing power losses. It is capable of driving large power MOSFETs with minimal switching losses, thanks to its high peak output currents of 3.7A source and 4.5A sink.
