Product details
Overview
TLE98322QVXUMA1 from Infineon Technologies is a single-chip 3-phase BLDC motor driver IC integrating ARM® Cortex®-M0 core, six N-channel high-side/low-side gate drivers, current sense amplifiers, and LIN physical layer. It operates up to 48 V supply, supports 10-bit ADC with 8 channels, and delivers real-time motor control for automotive HVAC blowers. Used in brushless DC motor control systems requiring integrated logic and power stage.
For engineers reviewing the TLE98322QVXUMA1 datasheet, TLE98322QVXUMA1 pinout, TLE98322QVXUMA1 application, or TLE98322QVXUMA1 equivalent, key selection criteria include integrated MCU architecture, gate driver voltage rating (48 V), current sensing capability, LIN interface compliance, and AEC-Q100 qualification status.
Technical Context
The TLE98322QVXUMA1 implements a dedicated motor control subsystem with hardware-based PWM generation, dead-time insertion, and overcurrent protection logic. Its embedded Cortex-M0 runs at up to 48 MHz and interfaces directly with three half-bridge gate drivers per phase, supporting 120° commutation and sensorless FOC via back-EMF monitoring.
It integrates a LIN 2.2A transceiver compliant with ISO 17987-4, enabling bidirectional communication at 19.2 kbps with wake-up capability. The device includes two independent current-sense amplifiers (gain = 20 V/V, offset < 1 mV) and a temperature sensor with ±2°C accuracy over -40°C to 150°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase BLDC motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN32F0B | Integrates STM32F0 MCU (Cortex-M0) but lacks LIN transceiver; uses SPI for host communication | Requires external LIN transceiver for vehicle network integration | Select when system already includes LIN master node and cost-sensitive design prioritizes MCU flexibility over integration |
| DRV3205-Q1 | Three-phase gate driver only - no MCU, ADC, or LIN; AEC-Q100 qualified | Needs external microcontroller and communication interface IC | Select when existing MCU platform handles control algorithm and only high-current gate driving is required |
Compared with STSPIN32F0B and DRV3205-Q1, the TLE98322QVXUMA1 uniquely combines full motor control stack (MCU + drivers + sensing + LIN) in one AEC-Q100 Grade 1 package - reducing BOM count, PCB area, and functional safety certification effort.

FAQ
What is the maximum continuous output current supported by the TLE98322QVXUMA1?
The TLE98322QVXUMA1 does not drive motors directly; it drives external N-channel MOSFETs. Its gate drivers support peak sink/source currents of 200 mA/100 mA per channel, enabling use with MOSFETs rated for ≥30 A RMS phase current when properly heatsinked and operated within thermal limits.
Does the TLE98322QVXUMA1 support field-oriented control (FOC)?
Yes - the device supports sensorless FOC through its hardware-accelerated back-EMF observer, 10-bit ADC with simultaneous sampling, and dedicated PWM timers with center-aligned mode. Firmware implementation requires Infineon's DAVE™ IDE and motor control library, which provide validated FOC kernels.
Is the internal temperature sensor calibrated at production?
Yes - each TLE98322QVXUMA1 undergoes factory calibration for the internal temperature sensor. Output voltage is trimmed to 25°C reference point with ±2°C accuracy over the full operating range (-40°C to +150°C), and calibration coefficients are stored in OTP memory.
Can the LIN interface operate independently of the MCU core?
Yes - the LIN transceiver includes autonomous wake-up detection and can assert the WAKE pin without CPU intervention. During deep-sleep mode, the LIN physical layer remains active and responds to dominant pulses, allowing the MCU to remain powered down until valid frame reception.
