This document describes the features and characteristics of the CoreControl TM TDA21107 product, including fast rise and fall times, adjustable high-side MOSFET gate drive voltage, adaptive gate drive control, support for shutdown mode, and compatibility with standard PWM controller ICs.
The TDA21107 CoreControl is a dual high‑speed driver designed to drive N‑Channel low‑side and high‑side MOSFETs in half‑bridge circuits. It offers fast rise and fall times up to 1 MHz, adaptive gate‑drive control to prevent cross‑conducting, and a range of protection features including shutdown mode and over‑voltage protection.
The datasheet details the pinout, block diagram, absolute maximum ratings, thermal and electrical characteristics, and typical application circuits such as voltage regulator modules, DC‑DC converters and Class‑D amplifiers. It also lists worldwide sales offices for Infineon.
