TLE9877QXA40XUMA3

Overview

The TLE9877QXA40XUMA3 is an automotive-grade single-chip 3-phase motor driver from Infineon's MOTIX family. It integrates an ARM Cortex-M3 core operating at 40 MHz with 64 kB Flash and 6 kB RAM. The device features six fully integrated NFET drivers optimized for external power MOSFETs, a charge pump for low-voltage operation, and programmable current control. Key peripherals include a high-speed operational amplifier for shunt-based current sensing, a LIN transceiver compatible with LIN 2.2, two UARTs, and multiple ADC modules. It operates within a supply voltage range of 5.5 V to 28 V and supports temperatures from -40°C to +150°C.

Feature Summary

• Integrates ARM Cortex-M3 core (40 MHz) with 64 kB Flash and 6 kB RAM for advanced algorithms like FOC.
• Includes six current-programmable NFET drivers with charge pump and EMC-optimized current slope control.
• Features integrated LIN 2.2 transceiver, two full-duplex UARTs, and high-speed op-amp for current sensing.
• Provides comprehensive analog peripherals including 8-bit and 10-bit ADCs, temperature, and battery voltage measurement.

Applications

• Engine cooling fans
• HVAC blowers
• Water pumps and BLDC pumps/fans
• Fuel pumps

Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) in official Infineon documentation before finalizing designs. Confirm that the XUMA3 suffix corresponds to the specific tape-and-reel packaging configuration required for production. Ensure compliance with AEC-Q100 automotive qualification standards relevant to the target application environment.

Selection Notes

Select this model for applications requiring sensorless or sensor-based BLDC motor control via LIN or PWM interfaces. The integrated high-speed op-amp makes it suitable for shunt-based current sensing without external amplifiers. Consider the VQFN-48 package thermal performance for high-temperature automotive environments up to 150°C.

Part Context

This part belongs to the TLE987x product family, specifically designed for cost-effective and space-efficient electromechanical solutions. It serves as a highly integrated solution for automotive BLDC motor drives, combining MCU, gate drivers, and communication interfaces on a single chip to reduce system complexity.

Replacement Considerations

Check Infineon's official selection guides for direct pin-to-pin replacements within the TLE9877 series, such as variants with different memory sizes or package options (e.g., TLE9877QXA40). Verify software compatibility if migrating between closely related members of the MOTIX family.
