L6208D013TR

Overview

The L6208D013TR is a fully integrated bipolar stepper motor driver manufactured by STMicroelectronics. It utilizes DMOS technology to combine power transistors with control logic on a single chip. The device supports an operating supply voltage range of 8 V to 52 V and delivers a continuous output current of 2.8 A with a peak capability of 5.6 A. It features a typical on-resistance of 0.3 Ω at 25 °C and operates at frequencies up to 100 KHz. The component is housed in a PowerSO-36 surface-mount package and functions within a temperature range of -40 °C to +150 °C.

Feature Summary

• Integrates dual independent constant off-time PWM current controllers for precise chopping regulation.
• Includes non-dissipative overcurrent protection on high-side MOSFETs and thermal shutdown capabilities.
• Provides fast/slow decay mode selection and quasi-synchronous rectification for optimized motor performance.
• Features built-in decoding logic supporting both full-step and half-step drive sequences.

Applications

• Bipolar stepper motor control systems
• Industrial automation and motion control applications
• General purpose motor driver circuits

Procurement Notes

Verify the specific ordering suffix D013TR against official manufacturer documentation to confirm the PowerSO-36 package configuration and reel packaging details. Ensure that design implementations account for the component's humidity sensitivity classification and adhere to recommended soldering profiles for surface-mount assembly.

Selection Notes

Select this component when a fully integrated solution for bipolar stepper motors is required, eliminating the need for external discrete drivers. Consider its 2.8 A continuous current rating and 52 V maximum voltage limit relative to the target motor specifications. Evaluate the PowerSO-36 package suitability for thermal management and PCB space constraints compared to alternative packages like SO24.
