The TLE7181EM is a H-bridge driver IC dedicated to control 4 N-channel MOSFETs typically forming the converter for a high current DC motor drives in the automotive sector. It incorporates several protection features such as over current and short circuit detection as well as under-, over voltage and over temperature diagnosis. Typical applications are fans, pumps and electric power steering. The TLE7181EM is designed for a 12V power net.
