Product details
Overview
TLE9831QVXUMA1 from Infineon Technologies is a single-chip 3-phase BLDC motor driver IC integrating an ARM® Cortex®-M0 core, six N-channel pre-driver outputs, integrated charge pump, and embedded linear voltage regulators (5 V/40 mA and 3.3 V/40 mA). It supports up to 48 V supply, delivers 1 A gate drive current per channel, and operates from -40 °C to 150 °C ambient. Used in automotive HVAC blower and radiator fan control systems.
For engineers reviewing the TLE9831QVXUMA1 datasheet, TLE9831QVXUMA1 pinout, TLE9831QVXUMA1 application, or TLE9831QVXUMA1 equivalent, key selection criteria include integrated MCU architecture, gate drive capability, on-chip voltage regulation, thermal performance at 150 °C, and qualification per AEC-Q100 Grade 1.
Technical Context
The TLE9831QVXUMA1 implements a dedicated motor control subsystem with hardware-based PWM generation, analog front-end for current sensing (two differential inputs), and configurable watchdog timer. Its embedded M0 core runs at up to 48 MHz and includes 64 KB Flash, 6 KB RAM, and boot ROM with UART bootloader.
It integrates a high-side/low-side gate driver stage with programmable dead-time insertion, overcurrent protection via external shunt sensing, and thermal shutdown with hysteresis. The device uses a single 48 V supply and generates all internal rails without external LDOs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase BLDC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN32F0B | Integrated 32-bit ARM Cortex-M0+ (72 MHz), no embedded 48 V regulator; requires external buck converter for 5 V/3.3 V rails | Lacks AEC-Q100 qualification; rated for industrial (-40 °C to +125 °C), not automotive under-hood use | Select when cost-sensitive industrial BLDC designs prioritize higher CPU clock over automotive qualification. |
| DRV3205-Q1 | Three-phase gate driver only (no MCU); requires external microcontroller and separate LDOs for logic rails | Supports higher gate drive current (2 A) and wider voltage range (5–60 V), but increases system component count by ≥7 | Select when existing MCU platform must be retained and maximum flexibility in control algorithm is required. |
Compared with STSPIN32F0B and DRV3205-Q1, the TLE9831QVXUMA1 provides the highest integration density for automotive-grade BLDC control-reducing total solution size by 40% and eliminating four external components while maintaining AEC-Q100 compliance and built-in safety mechanisms.

FAQ
What communication interfaces does the TLE9831QVXUMA1 support?
The TLE9831QVXUMA1 features a single-wire UART interface compliant with ISO 9141-2, supporting firmware updates and debug communication at up to 115.2 kbps. It does not include CAN, LIN, or SPI peripherals-those functions require external transceivers or are implemented in host MCU firmware.
Does the TLE9831QVXUMA1 include hardware-based current sensing?
Yes-it integrates two differential analog inputs (CS0, CS1) with programmable gain (1× or 4×) and offset calibration, directly interfacing with low-side shunt resistors. The internal 10-bit ADC digitizes sensed currents with 1 µs conversion time and supports synchronous sampling with PWM triggers.
Can the TLE9831QVXUMA1 drive P-channel high-side MOSFETs?
No-the TLE9831QVXUMA1's gate drivers are optimized for N-channel high-side and low-side configurations only. Its charge pump supports N-channel high-side driving up to 48 V, and it lacks bootstrap diode integration or level-shifting circuitry for P-channel devices.
Is the TLE9831QVXUMA1 qualified for functional safety standards?
Yes-it is designed to support ASIL-B compliance per ISO 26262. Key safety features include lockstep-capable clock monitoring, Flash ECC, RAM parity, ADC self-test, and configurable window watchdog-all accessible via the embedded safety library (SafeTlib) provided by Infineon.
