Overview
The L6207PD, produced by STMicroelectronics, is a DMOS dual full bridge driver designed for motor control applications. It is realized in MultiPower BCD technology, which integrates isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. This device is particularly suited for controlling bipolar stepper motors and dual DC motors. It features two independent constant off-time PWM current controllers, which perform the chopping regulation necessary for efficient motor control. The L6207PD is available in PowerSO36 and SO24 packages, offering a range of options for different design requirements.
