TLE9879QTW40XUMA1

Application Specific Microcontrollers Overview

The Infineon TLE9879QTW40XUMA1 is an automotive-grade System-on-Chip integrating a 32-bit Arm Cortex-M3 microcontroller with a BLDC MOSFET driver. Operating on a single supply of 5.5 V to 28 V, it features a 40 MHz core, 128 KB flash, and 6 KB RAM. The device includes a LIN 2.2 transceiver, high-speed operational amplifier for shunt current sensing, and a bridge driver with charge pump. It supports an extended junction temperature range of -40°C to +175°C and is packaged in a TQFP-48-10 format.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix XUMA1 corresponds to the required tape-and-reel packaging configuration. Confirm that the TQFP-48-10 package variant meets the thermal and mechanical constraints of the target PCB layout. Ensure compatibility with the BF design step revision during component sourcing.

Application Specific Microcontrollers Selection Notes

Select this model when an extended junction temperature rating up to 175°C is required compared to standard grade devices. Choose the TQFP-48-10 package if through-hole mounting or specific pin accessibility is preferred over QFN options. Verify that the 128 KB flash capacity suffices for the application firmware before considering higher-memory variants.

Application Specific Microcontrollers Part Context

This component belongs to the MOTIX™ TLE9879 family of embedded power microcontrollers designed for automotive body electronics. It combines processing capabilities with power stage integration to reduce bill-of-materials count. The QTW40 designation specifically identifies the TQFP package and extended temperature grade within the product line.

Application Specific Microcontrollers Replacement Considerations

Direct replacements must match the TQFP-48-10 package and 175°C temperature grade. Other members of the TLE9879 family may require schematic adjustments due to differences in pinout or package type.
