L6225D ST DMOS Driver | 20-SO | 1.4A, 52V, Dual Full Bridge

Product Overview

The L6225D is a dual full-bridge DMOS driver manufactured by STMicroelectronics, designed for driving bipolar stepper motors or two DC motors. It integrates two independent full bridges, each capable of delivering up to 1.4 A RMS current and operating from a supply voltage up to 52 V. The device features a non-dissipative overcurrent protection, thermal shutdown, and a cross-conduction protection. The L6225D is housed in a 20-pin SO package, making it suitable for space-constrained applications.
