Product details
Overview
TLE9873QXW40XUMA1 from Infineon is a single-chip Arm® Cortex®-M3 automotive microcontroller integrating a 3-phase BLDC MOSFET driver, LIN 2.2 transceiver, and high-speed op-amp for shunt-based motor current sensing - all in a VQFN-48-29 package. It delivers 48 KB flash, 3 KB RAM, and operates from 5.5 V to 28 V across -40°C to +175°C junction temperature, targeting wiper, window lift, and auxiliary fan control.
For engineers reviewing the TLE9873QXW40XUMA1 datasheet, TLE9873QXW40XUMA1 pinout, TLE9873QXW40XUMA1 application, or TLE9873QXW40XUMA1 equivalent, this part supports AEC-Q100 Grade 0 qualification, on-chip clock generation via OSC/PLL, and integrated power management for single-supply automotive motor control systems.
Technical Context
The TLE9873QXW40XUMA1 integrates SCU-DM (digital system control), SCU-PM (power module), and dedicated motor control peripherals including CCU6 for 3-phase PWM generation and GPT12 timers for precise timing. Its power architecture includes independent 5.0 V (VDDP) and 1.5 V (VDDC) regulators plus external 5.0 V support (VDDEXT).
It implements LIN communication via an embedded LIN 2.2 transceiver with bus wake-up capability and uses its high-speed op-amp (gain-bandwidth product >1 MHz) for real-time current feedback in closed-loop BLDC commutation - eliminating need for external signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M3, 32-bit, up to 50 MHz - enables deterministic real-time motor control with nested vectored interrupt handling. |
| Memory | 48 KB flash + 3 KB RAM - sufficient for field-oriented control (FOC) algorithms and LIN protocol stack without external memory. |
| Supply Range | 5.5 V to 28 V single supply - directly interfaces automotive battery rail without pre-regulation stage. |
| Operating Temp | Tj = -40°C to +175°C (AEC-Q100 Grade 0) - qualified for under-hood motor actuator environments. |
| LIN Interface | Integrated LIN 2.2 transceiver with wake-up detection - reduces BOM count and PCB footprint vs discrete transceiver solutions. |
| MOSFET Driver | Integrated 3-phase gate driver with charge pump - drives external N-channel MOSFETs without bootstrap diodes or external high-side drivers. |
| Current Sensing | On-die high-speed op-amp (typ. 1.2 MHz GBW) optimized for shunt resistor amplification - enables accurate 10–100 mΩ shunt-based phase current measurement. |
Pinout & Package
VQFN-48-29 package: 48-pin, 7 mm × 7 mm, 0.5 mm pitch, exposed thermal pad, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBAT | Main power input | Accepts 5.5–28 V automotive supply; feeds internal PMU for all voltage domains. |
| VDDP | 5.0 V regulated output | Supplies digital logic, LIN transceiver, and GPIO; internally generated from VBAT. |
| VDDC | 1.5 V core supply | Powers Cortex-M3 core and memory subsystem; low-noise regulated output from PMU. |
| VS | High-side driver supply | Connects to external MOSFET source nodes; enables charge-pump-based high-side drive. |
| INx / OUTx | Gate driver inputs/outputs | Three half-bridge pairs (IN0–IN2, OUT0–OUT2) for 3-phase BLDC control with shoot-through protection. |
| AS, BS, CS | Shunt amplifier inputs | Differential inputs for motor phase current sensing via external shunt resistors. |
| TXD_LIN / RXD_LIN | LIN physical layer I/O | Direct connection to LIN bus; integrated transceiver handles level-shifting, slew-rate control, and wake-up filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated BLDC gate driver | Eliminates need for external high-side drivers or bootstrap circuits - simplifies layout and improves reliability in space-constrained modules. |
| On-chip LIN 2.2 transceiver | Reduces component count by one IC and associated passive filtering components - lowers system cost and board area. |
| High-speed current-sense op-amp | Enables real-time, low-latency phase current acquisition for fast-loop FOC or six-step commutation without external op-amp compensation. |
| Single-supply operation (5.5–28 V) | Removes requirement for external DC-DC converter or LDO pre-regulator - streamlines power architecture for 12 V/24 V vehicle platforms. |
| AEC-Q100 Grade 0 qualification | Validated for continuous operation at 175°C junction temperature - suitable for direct mounting on motor housings or high-ambient locations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive BLDC motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN32F0B | Integrated 3-phase driver + Cortex-M0 core (no LIN); 16 KB flash; max 125°C Tj. | Lacks LIN interface and Grade 0 temp rating - requires external transceiver and thermal derating in under-hood use. | Prefer when LIN is not required and ambient temperature stays below 125°C. |
| NXP S32K116 | Cortex-M0+ MCU only (no integrated gate driver or op-amp); requires external driver IC and current sense circuitry. | Higher flexibility but larger BOM and PCB area; supports CAN FD instead of LIN. | Prefer when multi-protocol connectivity (CAN+LIN) or functional safety ASIL-B decomposition is needed. |
Compared with STSPIN32F0B and S32K116, the TLE9873QXW40XUMA1 uniquely combines Grade 0 temperature capability, LIN 2.2, gate driver, and current-sense op-amp in one die - minimizing system-level complexity for cost-sensitive, thermally demanding automotive actuators.

FAQ
Does TLE9873QXW40XUMA1 support field-oriented control (FOC)?
Yes - its CCU6 unit provides complementary PWM outputs with dead-time insertion and GPT12 timers enable precise rotor position sampling. The 48 KB flash and 3 KB RAM accommodate standard FOC libraries, and the on-die op-amp supports real-time current reconstruction for two-shunt or three-shunt configurations.
What is the maximum motor voltage supported?
The device itself does not drive motors directly - it drives external N-channel MOSFETs. Its VS pin supports up to 28 V, and gate driver outputs swing rail-to-rail relative to VS. Motor voltage is limited only by the selected external MOSFETs' VDS rating and layout constraints.
Is external crystal required for operation?
No - the TLE9873QXW40XUMA1 includes an on-chip oscillator (OSC_HP) supporting both external crystal (1–20 MHz) and external clock input modes. Internal RC oscillator allows basic operation without external components, though crystal mode is recommended for LIN timing accuracy.
How is functional safety addressed?
The device includes watchdog timer (WDT1), memory protection unit (MPU), flash CRC checking, and lockstep-capable peripherals. While not ASIL-certified standalone, it supports ASIL-B decomposition when combined with appropriate software and system-level mechanisms per ISO 26262.
