L6205D013TR

Overview

The L6205D013TR is a dual full-bridge motor driver manufactured by STMicroelectronics, designed for controlling bipolar stepper and brushed DC motors. It utilizes BiCDMOS technology to integrate control logic and power stages on a single chip. The device supports an operating supply voltage range of 8V to 52V and delivers a continuous output current of 2.8A per bridge with peak currents up to 5.6A. It features a 20-SOIC package with a junction temperature rating from -25°C to 125°C.

Feature Summary

• Integrates four half-bridges into a complete dual full-bridge configuration for comprehensive motor control.
• Includes non-dissipative overcurrent protection and thermal shutdown mechanisms for enhanced reliability.
• Features integrated fast free-wheeling diodes and cross-conduction protection to simplify circuit design.

Applications

• Bipolar stepper motor control systems
• Brushed DC motor drives
• General-purpose motion control applications

Procurement Notes

Verify the specific package variant against project requirements, as the L6205 family includes SOIC-20 and PowerSO-20 options with different thermal characteristics. Confirm that the 2.8A continuous current rating aligns with the thermal management capabilities of the target PCB layout. Ensure supply voltage limits are respected within the 8V to 52V operational window.

Selection Notes

Select this component when a fully integrated solution for two independent motor channels is required without external discrete drivers. It is suitable for applications needing high-side MOSFET protection and parallel operation capabilities. Consider the thermal performance of the 20-SOIC package if continuous high-current operation is expected in confined spaces.

Part Context

This part belongs to the L6205 series of DMOS dual full-bridge drivers. It is part of STMicroelectronics' portfolio of motor control ICs utilizing MultiPower-BCD technology. The series is designed to provide robust performance for small to medium-power motor applications with integrated safety features.
