TLE52052GPAUMA1

Overview

The TLE52052GPAUMA1 is an automotive-grade brushed DC motor driver from Infineon's SPT series, designed for high-current applications. It integrates a parallel H-bridge configuration with DMOS technology, delivering a continuous output current of 5A and supporting supply voltages between 5.3V and 40V. The device features a low typical on-resistance of 200mΩ per switch at 25°C and operates within a junction temperature range of -40°C to 150°C. Packaged in a 20-DSO format with an exposed pad, it includes comprehensive protection mechanisms such as overtemperature shutdown with hysteresis, short-circuit protection, and load diagnostic capabilities via an open-drain error flag.

Feature Summary

• Integrates dual half-bridge DMOS power stages for efficient brushed DC motor control
• Includes built-in diagnostic functions for short-circuit and open-load detection
• Features robust protection against overtemperature conditions with automatic recovery
• CMOS/TTL compatible inputs ensure reliable interface with standard logic controllers

Applications

• Automotive window lift actuators
• Seat adjustment motors
• Wiper system drives
• Cooling fan control units

Procurement Notes

Verify the specific package variant, as the TLE52052 family includes both TO-263 and DSO configurations. Confirm that the 20-DSO footprint matches the target PCB design. Check for end-of-life status or alternative recommendations from the manufacturer due to potential production phase-outs. Ensure thermal management solutions account for the exposed pad requirement in this package type.

Selection Notes

Select this component when a single-chip solution for medium-power brushed DC motors is required in automotive environments. The parallel architecture allows for higher current handling compared to single-bridge variants. Consider the 20-DSO package for applications requiring multiple control lines or enhanced thermal dissipation through the exposed pad. Verify compatibility with the system's voltage rail, which must remain within the 5.3V to 40V operational window.

Part Context

This part belongs to the TLE5205 series, a family of integrated motor control ICs developed by Infineon Technologies. The series utilizes SPT (Single Power Technology) to combine bipolar, CMOS, and DMOS processes on a single chip. While other variants like the TLE52052GAUMA1 use a TO-263 package, the GPAUMA1 specifically utilizes a 20-pin DSO form factor, offering different pinout and thermal characteristics while maintaining core electrical performance.

Replacement Considerations

Direct substitutes may include other TLE52052 variants with different packaging, such as TLE52052GAUMA1 for TO-263 applications. Cross-reference pinouts carefully when replacing packages. Consult Infineon documentation for updated lifecycle status and recommended alternatives if this specific DSO variant is discontinued.
