TLE9891QTA61XUMA1

Overview

The Infineon TLE9891QTA61XUMA1 is a MOTIX™ microcontroller with an integrated 3-phase bridge driver and CAN-FD transceiver, designed for BLDC motor applications. It features a 32-bit Arm Cortex-M3 core operating at up to 60 MHz. The device includes up to 256 KB FLASH1 and 32 KB RAM, along with a single power supply range of 5.5 V to 28 V. Integrated peripherals include a 14-bit SDADC for rotary sensors, multiple timers (CCU7, GPT12), and analog comparators for BEMF detection. It supports automotive functional safety requirements up to ASIL-B via its safe switch-off path.

Feature Summary

• Integrated 3-phase N-FET bridge driver with charge pump and PWM generation
• Built-in CAN-FD protocol handler and transceiver
• 14-bit Sigma-Delta ADC (SDADC) for high-precision rotary sensor measurement
• ASIL-B compliant fail-safe mechanism with dedicated safe switch-off path

Applications

• Automotive auxiliary drives such as pumps and fans
• HVAC actuators and sunroof motors
• BLDC motor control systems requiring CAN-FD communication

Procurement Notes

Verify the specific ordering suffix XUMA1 corresponds to the tape-and-reel packaging format required for production. Confirm that the PG-TQFP-48 package variant matches the PCB footprint design. Ensure the selected memory configuration meets the application's code storage needs before finalizing procurement.

Selection Notes

Select this component when a combined MCU and gate driver solution is needed to reduce board space. The TLE9891 provides sufficient processing power for FOC algorithms while handling direct power stage driving. Verify that the 5.5 V to 28 V supply range aligns with the vehicle's electrical system specifications.

Part Context

This part belongs to the Infineon MOTIX™ TLE989x/TLE988x family of microcontrollers. These devices are specifically engineered for automotive body electronics and motor control applications. The TLE9891 variant integrates the highest level of peripheral connectivity within the series, including CAN-FD support.

Replacement Considerations

Check for other members of the TLE989x family with different memory sizes or pin counts. Verify compatibility with existing software drivers if migrating from previous generations like the TLE987x series.
