L6258EX Description

The L6258EX from STMicroelectronics is a high-performance DMOS motor driver IC designed for bipolar stepper and brushed DC motor control. This obsolete device delivers an output current of 1.2A per channel with a half-bridge (4) configuration, supporting precise motion control in industrial and general-purpose applications. Operating within a 4.75V–5.25V supply range and capable of driving loads from 12V to 40V, it integrates advanced DMOS technology for efficient power management and thermal performance, with a junction temperature rating of 150°C (TJ). Packaged in a 36-PowerSO tube, it features a parallel interface and offers flexible step resolution (1, 1/2, 1/4, 1/8, 1/16), making it ideal for applications requiring fine-tuned positioning.

L6258EX Features

• High Current Output: 1.2A per channel for robust motor driving.
• Wide Voltage Range: Supports 12V–40V load voltage, adaptable to diverse systems.
• Flexible Step Resolution: Configurable microstepping (1/16th step) for smooth motion control.
• DMOS Technology: Enhances efficiency and thermal dissipation.
• Parallel Interface: Simplifies integration with microcontrollers.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.
• Surface-Mount Design: Compact 36-PowerSO package for space-constrained PCB layouts.
• High-Temperature Operation: Rated for 150°C (TJ), suitable for demanding environments.

L6258EX Applications

The L6258EX excels in applications requiring precision and reliability, such as:

• Industrial Automation: CNC machines, robotic arms, and conveyor systems.
• Office Equipment: Printers, scanners, and paper-feed mechanisms.
• Medical Devices: Pump controls and diagnostic instrument positioning.
• Consumer Electronics: Camera gimbals and automated home appliances.
  Its microstepping capability and bipolar stepper support make it particularly valuable in systems needing smooth, low-vibration motion.

Conclusion of L6258EX

While marked obsolete, the L6258EX remains a robust solution for bipolar stepper and brushed DC motor control, offering a blend of high current output, thermal resilience, and configurable resolution. Its DMOS technology and wide voltage range cater to industrial and precision applications, though designers should consider modern alternatives for new projects. Legacy systems leveraging its parallel interface and microstepping flexibility continue to benefit from its performance.
