L6235D013TR

Overview

The L6235D013TR is a fully integrated three-phase DMOS motor driver designed for brushless DC (BLDC) applications. It operates within an 8 V to 52 V supply range and delivers a peak output current of 5.6 A, with a continuous DC rating of 2.8 A. The device features a typical on-resistance of 0.3 Ω at 25 °C and supports operating frequencies up to 100 kHz. It integrates a constant off-time PWM current controller, diagnostic outputs, and hall sensor decoding logic for 60° and 120° configurations.

Feature Summary

• Integrates isolated DMOS power transistors with CMOS and bipolar circuits on a single chip
• Includes non-dissipative overcurrent protection and thermal shutdown mechanisms
• Features built-in decoding logic for single-ended hall sensors to generate power stage sequences
• Provides slow decay synchronous rectification and cross-conduction protection

Applications

• Three-phase brushless DC motor control systems
• Industrial motion control drives
• Automotive ignition and engine management controllers

Procurement Notes

Verify the specific suffix D013TR against the manufacturer's official datasheet to confirm package type and reel specifications. Ensure compatibility with the required hall sensor configuration and voltage levels. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Confirm that the procurement source provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a highly integrated solution for three-phase BLDC motors is required. It is suitable for applications needing robust protection features such as overcurrent and thermal shutdown without external discrete components. Consider the 5.6 A peak current capability and 0.3 Ω on-resistance for efficiency requirements. Verify that the operating frequency range up to 100 kHz meets the system's switching needs.
