TLE7183QUXUMA9

Overview

The TLE7183QUXUMA9 is a three-phase driver IC from Infineon’s MOTIX family, designed for automotive BLDC motor applications. It integrates six half-bridge drivers to control external MOSFETs. The device operates within a supply voltage range of 5.5 V to 20 V and supports junction temperatures from -40°C to 150°C. Key electrical characteristics include an operating supply current of 110 mA, output voltage of 1.2 V, and power dissipation of 2 W. It features AEC-Q100 qualification and utilizes a QFN-48 package.

Feature Summary

• Integrates six half-bridge gate drivers for controlling up to six external N-channel MOSFETs in three-phase configurations.
• Includes integrated charge pumps and bootstrap diodes to simplify external component requirements.
• Provides comprehensive diagnostic capabilities including over-current, over-temperature, and undervoltage lockout protection.
• Supports PWM control interfaces with configurable dead-time insertion for reliable switching.

Applications

• Brushless DC (BLDC) motor drives in automotive systems
• Electric power steering (EPS) actuators
• Thermal management fans and pumps
• Window lifters and seat adjusters

Procurement Notes

Verify the specific suffix XUMA9 confirms the reel packaging format and tape width. Confirm AEC-Q100 grade compliance if automotive reliability is required. Check for end-of-life status as some variants may be NRND. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Selection Notes

Select this part when driving external MOSFETs rather than using integrated switches. Compare against TLE7183FXUMA9 for package differences. Consider thermal performance requirements given the 2 W dissipation rating. Verify input logic levels match the system microcontroller interface.

Part Context

Part of the MOTIX TLE7183 series, which provides integrated solutions for three-phase motor control. The QU variant specifically denotes the QFN-48 package configuration. This series is optimized for automotive environments requiring high reliability and compact form factors.

Replacement Considerations

TLE7183FXUMA9 offers similar functionality but in a different package type. Verify pin compatibility before substitution. No direct drop-in replacements exist with identical feature sets; evaluate design modifications for alternative drivers.
