TLE52052SAKSA1

Overview

The TLE52052SAKSA1 is an automotive-grade DC motor driver manufactured by Infineon Technologies. It integrates a high-side and low-side DMOS power stage to form a single H-bridge configuration, designed for driving brushed DC motors in vehicle applications. The device operates within a supply voltage range of 6V to 40V and delivers a continuous output current of 5A with peak capabilities up to 6A. It utilizes the SPT (Super Junction Power Technology) process to combine bipolar control circuits with DMOS power devices on a single monolithic structure. The component features a TO-263-7 surface-mount package and supports CMOS/TTL compatible logic inputs.

Feature Summary

• Integrates a complete H-bridge circuit with DMOS output stages for efficient DC motor control
• Includes comprehensive protection mechanisms such as over-temperature shutdown, short-circuit protection, and undervoltage lockout
• Features diagnostic outputs for open-load and short-circuit detection via an error flag pin
• Built-in freewheeling diodes eliminate the need for external components in the commutation path

Applications

• Automotive window lift actuators
• Seat adjustment motor control systems
• Wiper system drive units
• Sunroof and convertible top mechanisms

Procurement Notes

Verify the specific suffix 'SAKSA1' against official Infineon documentation to confirm the exact tape-and-reel packaging configuration and lot traceability requirements. Ensure that the ordering part number matches the intended revision level, as suffixes may indicate variations in manufacturing date codes or specific customer customization requests rather than functional differences. Cross-reference the datasheet version to validate compatibility with current automotive standards.

Selection Notes

Select this component when a robust, single-channel H-bridge solution is required for automotive environments. It is suitable for applications demanding high thermal stability and integrated fault diagnostics. Consider the TO-263-7 package for its thermal dissipation capabilities relative to smaller surface-mount options. Evaluate the 5A continuous current rating against the motor's stall and running currents to ensure adequate headroom for transient loads.

Part Context

This part belongs to the TLE5205 series of single H-bridge motor drivers from Infineon. The series is characterized by its integration of control logic and power stages using specialized semiconductor processes. Variants within the family typically share core electrical specifications but differ in packaging styles, such as TO-220 or DSO formats, to accommodate different PCB layout constraints and thermal management strategies in automotive electronics.

Replacement Considerations

Direct replacements include other TLE5205 variants like TLE5205-2G or TLE5205-2GP, provided the pinout and package dimensions are compatible. Verify that any substitute maintains AEC-Q100 qualification and similar thermal resistance characteristics to ensure reliable operation in automotive under-hood or chassis applications.
