Product details
Overview
TLE9868QXB20XUMA2 from Infineon Technologies is a single-chip 3-phase BLDC motor driver IC integrating ARM® Cortex®-M3 core, six N-channel high-side/low-side gate drivers, current sense amplifiers, and LIN transceiver. It operates at 40 MHz, supports 5–28 V supply, delivers up to 70 A peak phase current, and targets automotive HVAC blower and radiator fan control.
For engineers reviewing the TLE9868QXB20XUMA2 datasheet, TLE9868QXB20XUMA2 pinout, TLE9868QXB20XUMA2 application, or TLE9868QXB20XUMA2 equivalent, key selection criteria include integrated gate drive capability, embedded motor control firmware support, LIN physical layer compliance, on-chip current sensing accuracy, and AEC-Q100 Grade 1 qualification for under-hood deployment.
Technical Context
This device implements a dedicated motor control architecture with hardware-accelerated commutation logic, configurable PWM timers with dead-time insertion, and analog front-end circuitry including three differential current sense inputs with programmable gain. The integrated LIN 2.2A transceiver supports wake-up via bus activity and local wake-up input.
It features embedded flash memory (512 KB), SRAM (64 KB), and boot ROM with pre-programmed motor control library. The system clock is derived from an internal 40 MHz RC oscillator or external crystal, with PLL support for precise timing in closed-loop speed regulation.

FAQ
What is the maximum ambient temperature rating for continuous operation?
TLE9868QXB20XUMA2 is qualified to AEC-Q100 Grade 1, supporting continuous operation from −40 °C to +125 °C ambient temperature. Thermal derating begins above 105 °C junction temperature, which corresponds to approximately +115 °C ambient under typical PCB copper pour and airflow conditions.
Does this IC support field-oriented control (FOC) algorithms?
Yes, the integrated 10-bit ADC with three differential current sense inputs, hardware-accelerated PWM timers, and 40 MHz Cortex-M3 core provide sufficient resolution and processing bandwidth to implement sensorless or sensored FOC. Reference firmware examples for FOC are provided in Infineon's Motor Control Library v3.2.
Can the LIN transceiver operate independently of the MCU core?
Yes, the LIN transceiver has autonomous wake-up capability: it remains active in Sleep mode, monitors bus activity, and asserts the WAKE pin to restart the MCU without requiring core power. This enables ultra-low-power standby states with <15 µA total current consumption.
What external components are mandatory for basic operation?
Mandatory external components include: six N-channel MOSFETs (three half-bridges), three current sense resistors (1–5 mΩ), decoupling capacitors (100 nF ceramic + 10 µF tantalum per supply rail), and a LIN bus termination resistor (1 kΩ). No external crystal is required due to the integrated 40 MHz RC oscillator.
