Product Introduction

Overview

The L6201PS is a monolithic full bridge switching motor driver produced by STMicroelectronics. It is realized in the Multipower-BCD technology, which integrates isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. This technology allows for optimized logic circuitry and power stages, achieving high performance and efficiency. The device is particularly suited for controlling DC motors, providing the necessary power stage for both speed and direction control.
