TLE9893QKW62SXUMA1

Overview

The Infineon TLE9893QKW62SXUMA1 is a MOTIX™ microcontroller designed for BLDC motor applications. It integrates an Arm Cortex-M3 core operating at up to 60 MHz with 256 KB FLASH1 and 32 KB RAM. The device features a single power supply range of 5.5 V to 28 V, a 3-phase bridge driver with charge pump, and CAN-FD communication. Peripheral interfaces include two UARTs (LIN support), two SSCs, multiple ADCs (12-bit, 10-bit, 14-bit SDADC), and timers. It supports automotive temperatures from -40°C to 175°C and includes safety mechanisms compliant with ISO 26262 ASIL B.

Feature Summary

• Arm Cortex-M3 core running at 60 MHz with 256 KB FLASH1 and 32 KB RAM
• Integrated 3-phase bridge driver with charge pump and safe switch-off path
• CAN-FD protocol handler and transceiver for high-speed communication
• Multiple analog peripherals including 12-bit ADC, 10-bit ADC, and 14-bit SDADC

Applications

• Automotive auxiliary drives such as pumps and fans
• HVAC blower motors
• Actuators and sunroof systems

Procurement Notes

Verify the specific ordering suffix SXUMA1 corresponds to the LQFP-64 package configuration. Confirm that the component meets AEC-Q100 qualification requirements for the intended automotive environment. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this model when a 3-phase BLDC driver with integrated CAN-FD is required. The LQFP-64 package provides sufficient GPIO count for complex control loops. Verify that the 256 KB memory capacity accommodates the firmware size and data storage needs for sensorless or sensor-based control algorithms.

Part Context

This part belongs to the Infineon MOTIX™ TLE989x family of microcontrollers. These devices are specifically engineered for intelligent 3-phase brushless DC motor control in automotive environments. The family offers scalable memory and clock frequencies while maintaining a compact footprint and low system cost through high integration.

Replacement Considerations

Consult the official TLE989x/TLE988x Errata Sheet and product selection guide for verified cross-references within the MOTIX™ portfolio. Substitution requires matching the package type, memory configuration, and pinout compatibility.
