The Infineon Technologies TDA21231AUMA1 is a DrMOS Half Bridge driver designed for high-efficiency synchronous buck converters. This device integrates the driver and MOSFETs into a single package, the PG-IQFN-31-2, for reduced board space and improved thermal performance. It features a 55A output current capability and a wide operating voltage range for the load (5V to 16V) and supply (4.5V to 7V). The TDA21231AUMA1 includes integrated bootstrap circuitry for efficient high-side gate drive and robust fault protection mechanisms, including shoot-through and undervoltage lockout (UVLO). Its PWM interface facilitates precise control. This component is commonly employed in power supply designs for computing, networking, and industrial applications. The TDA21231AUMA1 is supplied in Tape & Reel (TR) packaging and operates across a junction temperature range of -40°C to 150°C.
