TLE9877QXA40XUMA2

Overview

The TLE9877QXA40XUMA2 is a System-on-Chip (SoC) motor driver from Infineon's MOTIX family, integrating an ARM Cortex-M3 core with embedded power stages. Designed for automotive applications, it supports three-phase brushless DC (BLDC) motor control. The device operates within a supply voltage range of 5.5 V to 27 V and features a maximum operating temperature of +150°C. It is housed in a 48-VFQFN exposed pad package and holds AEC-Q100 qualification. Key electrical parameters include a working supply current of 30 mA and an output current capability of 50 mA.

Feature Summary

• Integrates ARM Cortex-M3 processor with 64 kB Flash memory for complex motor control algorithms.
• AEC-Q100 qualified for automotive reliability standards.
• Supports 3-phase BLDC motor control with integrated power stages.
• Operates over an extended temperature range from -40°C to +150°C.

Applications

• Automotive cooling fan control
• Electric window and sunroof actuators
• Seat adjustment motors

Procurement Notes

Verify the specific suffix XUMA2 indicates reel packaging when ordering. Confirm that the 48-VFQFN package variant matches the design footprint requirements. Ensure compatibility with the 5.5 V to 27 V input voltage range for the target application. Check for moisture sensitivity level (MSL) handling requirements during assembly.

Selection Notes

Select this component for applications requiring integrated MCU and power stage in a compact form factor. Compare against TLE9879 variants if higher memory capacity (128 kB) is needed. Ensure the 50 mA output current rating suffices for the load. Verify interface requirements such as LIN or UART availability on the specific pinout.

Part Context

This part belongs to the TLE987x series of embedded power microcontrollers. It shares the same core architecture and package style as other members like the TLE9879, differing primarily in memory size and specific feature sets. The MOTIX branding denotes its focus on motor drive solutions.

Replacement Considerations

TLE9879QXA40XUMA2 offers identical pinout and functionality but includes 128 kB Flash instead of 64 kB. This allows for upward compatibility if code space expansion is required without hardware changes.
