TLE9879QXW40XUMA1

Overview

The TLE9879QXW40XUMA1 is an automotive-grade System-on-Chip (SoC) microcontroller from Infineon's MOTIX™ Embedded Power family. It integrates a 32-bit ARM Cortex-M3 core with 128 kB Flash and 6 kB RAM, operating at a maximum clock frequency of 40 MHz. The device features a monolithic B6 bridge motor driver with charge pump, supporting power outputs up to 150 W. Key peripherals include two differential 14-bit Sigma-Delta ADCs, a high-speed operational amplifier for current sensing, and communication interfaces such as LIN 2.2, UART, and SSC. It operates on a single supply voltage ranging from 5.5 V to 28 V and is qualified to AEC-Q100 standards.

Feature Summary

• Integrated B6 bridge motor driver with charge pump for direct MOSFET control
• ARM Cortex-M3 core with 128 kB Flash and 6 kB RAM
• Two differential 14-bit Sigma-Delta ADCs and high-speed op-amp for sensorless FOC
• LIN 2.2 transceiver and standard communication interfaces (UART, SSC)
• AEC-Q100 qualified for automotive applications with -40°C to +175°C junction temperature range

Applications

• Brushless DC (BLDC) motor control in automotive systems
• Electric window and seat actuators
• Cooling fans and pumps
• Power tools and RC vehicles

Procurement Notes

Verify the specific suffix XUMA1 against the latest official datasheet to confirm package variant and marking details. Confirm availability status directly with authorized distributors, as production cycles may vary. Ensure compliance with RoHS3 specifications and check for any relevant errata sheets for the TLE987xQX family before finalizing procurement.

Selection Notes

Select this component for applications requiring integrated motor drive and control in a compact form factor. The 48-VFQFN package is suitable for surface-mount assembly. Consider the 175°C max junction temperature for high-thermal environments. Verify that the 10 available I/O pins and specific interface requirements (LIN, UART) match the system design needs.

Part Context

This part belongs to the Infineon TLE9879 QX series, designed specifically for embedded power applications. It differs from other variants like the TLE9879QXA40 primarily by its package type (VQFN-48-29 vs VQFN-48-31/79) and potentially internal trimming or marking, while sharing the same core MCU and driver architecture.

Replacement Considerations

Check for updated revisions within the same series, such as TLE9879QXW40XUMA2 or XUMA3, which may offer pin-compatible upgrades or enhanced features. Consult the manufacturer's obsolescence notices and recommended replacement lists for long-term supply chain stability.
