L6219-LF – STMicroelectronics

The STMicroelectronics L6219-LF is a DMOS fully integrated driver for stepper motors with built-in overcurrent protection, short-circuit protection, and thermal shutdown. Operating from a single supply, it provides a typical output voltage rating of 48V and can deliver up to 1.5A output current per channel continuously. The L6219-LF employs a non-dissipative overcurrent detection, enhancing efficiency and reducing power dissipation. Housed in a PowerSO-20 package, this SMD device offers a compact footprint ideal for space-constrained applications. Its operating temperature range spans from –25°C to 125°C, ensuring reliable performance in diverse environments. Typically used in applications like textile machinery, robotics, and automated positioning systems, the L6219-LF simplifies circuit design by integrating power stages and protection features, minimizing external component count and board space.
