TLE52052AKSA1

Overview

The TLE52052AKSA1 is an automotive-grade H-bridge motor driver manufactured by Infineon Technologies, belonging to the TLE5205 series. It integrates a single power H-bridge with DMOS output technology for driving DC motors in vehicle applications. The device supports a supply voltage range of 6V to 40V and delivers a continuous output current of 5A with a peak capability of 6A. It features a low typical on-resistance of 200mΩ per switch at 25°C. The component operates within a junction temperature range of -40°C to 150°C and is housed in a TO-263-7 package. It holds AEC-Q100 qualification and complies with RoHS standards.

Feature Summary

• Integrates a high-current H-bridge using SPT (Single Power Technology) process combining bipolar control circuits with DMOS power devices.
• Provides comprehensive protection mechanisms including full short-circuit protection, over-temperature protection with hysteresis, and load diagnostic capabilities for open and short circuits.
• Features CMOS/TTL compatible inputs with hysteresis to prevent cross-conduction currents during switching transitions.
• Includes internally integrated freewheeling diodes, reducing external component requirements to a single power decoupling capacitor.

Applications

• Brushed DC motor control in automotive systems
• Actuator drive circuits requiring H-bridge topology
• Automotive electronic control units (ECUs)

Procurement Notes

Verify the specific suffix 'AKSA1' against official Infineon documentation to confirm exact tape-and-reel specifications and marking details. Confirm availability status as distribution channels may list this part as obsolete or end-of-life. Ensure the ordering part number matches the required package variant and quality grade before finalizing procurement orders.

Selection Notes

Select this component when a robust, single-channel H-bridge solution is required for automotive DC motor applications. It is suitable for designs needing high current handling up to 6A peak with integrated thermal and electrical protection. Consider the TO-263-7 package constraints for PCB layout and thermal management requirements relative to the expected duty cycle and ambient operating conditions.

Part Context

This part belongs to the TLE5205 family of motor drivers from Infineon, designed specifically for automotive environments. The series utilizes advanced BCDMOS technology to integrate logic control and power stages on a single die. Other variants in this family include TLE52052GAUMA1 and TLE52052GNTMA1, which share similar core electrical characteristics but may differ in packaging or reel specifications.

Replacement Considerations

Direct substitutes within the same functional family include TLE52052GAUMA1 and TLE52052GNTMA1. Verify pin compatibility and thermal performance equivalence before substitution. Cross-reference with updated Infineon product selection guides to ensure no newer generations have superseded these legacy parts.
