TLE7184F3VXUMA1

Overview

The TLE7184F3VXUMA1 is a system IC designed for brushless DC (BLDC) and brushed DC motor drives, operating within a supply voltage range of 6 V to 45 V. It integrates three half-bridge pre-drivers with power MOSFETs in a PG-VQFN-48-14 package. Key electrical parameters include a maximum output current of 350 mA per channel and an operating frequency up to 25 kHz. The device features a built-in 3.3 V / 70 mA voltage regulator and supports PWM control interfaces. It is qualified to AEC-Q100 standards and operates across a temperature range of -40 °C to +150 °C.

Feature Summary

• Integrates three half-bridge pre-drivers with parallel power MOSFETs for efficient motor phase control.
• Includes integrated diagnostic capabilities such as overcurrent, short circuit, and overtemperature protection.
• Features a dedicated 3.3 V linear voltage regulator providing up to 70 mA for external sensor or logic supply.
• Supports advanced control functions including deadtime control and direction management for BLDC applications.

Applications

• Brushless DC (BLDC) motor drives in automotive systems
• Brushed DC motor control applications
• Automotive cooling fan controllers
• Window lift and seat adjustment actuators

Procurement Notes

Verify the specific suffix XUMA1 to confirm tape-and-reel packaging and lead-free status. Confirm end-of-life status as distribution channels may vary. Ensure compatibility with existing PCB footprints for the PG-VQFN-48-14 package. Check for any required design-in documentation from Infineon for automotive qualification compliance.

Selection Notes

Select this component for applications requiring integrated power switching and control logic in a compact form factor. The wide supply voltage range suits 12 V and 24 V automotive architectures. Consider the thermal performance of the exposed pad design for high-current continuous operation. Verify that the integrated diagnostics meet the safety requirements of the target application.

Part Context

This part belongs to the TLE7184 family of motor driver ICs from Infineon Technologies. It is specifically engineered for automotive-grade reliability, adhering to AEC-Q100 standards. The device consolidates gate drivers, power stages, and control logic into a single solution, reducing bill-of-materials complexity compared to discrete implementations.

Replacement Considerations

Check for direct pin-to-pin replacements within the TLE7184 series, such as variants with different suffixes indicating packaging or temperature grades. Verify functional equivalence if substituting with other BLDC driver ICs, ensuring matching voltage ratings and current capabilities.
