L6207QTR

Full Half-Bridge (H Bridge) Drivers Overview

The L6207QTR is a DMOS dual full bridge motor driver manufactured by STMicroelectronics, designed for robust motor control applications. It integrates two independent constant off-time PWM current controllers for precise chopping regulation. The device supports an operating supply voltage range from 8 V to 52 V and delivers a peak output current of 5.6 A with a continuous DC current of 2.8 A per channel. It features a typical on-resistance of 0.3 Ω at Tj= 25 °C and operates at frequencies up to 100 KHz. Packaged in PowerSO-36, it includes non-dissipative overcurrent protection, thermal shutdown, cross-conduction protection, and undervoltage lockout.
