Product details
Overview
TLE9877QXW40XUMA2 from Infineon Technologies is a single-chip 3-phase BLDC motor driver IC integrating ARM® Cortex®-M3 core, six N-channel pre-driver outputs, integrated LIN transceiver, and embedded voltage regulators (5V/3.3V). It operates at up to 40 MHz, supports 12-bit ADC with 16 channels, and delivers 120 mA gate drive current per high-side channel. Used in automotive HVAC blower and radiator fan control systems.
For engineers reviewing the TLE9877QXW40XUMA2 datasheet, TLE9877QXW40XUMA2 pinout, TLE9877QXW40XUMA2 application, or TLE9877QXW40XUMA2 equivalent, key selection criteria include integrated LIN physical layer compliance, on-chip current sensing capability, programmable dead-time control, and AEC-Q100 Grade 1 qualification for under-hood operation.
Technical Context
The TLE9877QXW40XUMA2 implements a dedicated motor control architecture with hardware-accelerated PWM generation, real-time current measurement via integrated shunt amplifiers, and configurable fault protection including overcurrent, overtemperature, and undervoltage lockout. Its LIN interface complies with ISO 17987-4:2016 and supports auto-baud detection.
On-chip power management includes a 5 V low-dropout regulator for internal logic and external peripherals, plus a 3.3 V LDO for the microcontroller core. The device features a 12-bit SAR ADC with hardware-triggered sampling synchronized to PWM edges for precise current loop timing.

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 |
|---|---|---|---|
| TLE9879QXW40XUMA2 | Includes additional CAN FD interface and enhanced watchdog with windowed timeout; same pinout and firmware-compatible | Required where ECU communication mandates CAN FD instead of LIN-only topology | Select when system architecture requires dual-bus (LIN + CAN FD) connectivity without PCB redesign |
| MC33816AE | 8-bit S12Z core, no integrated LIN, requires external LIN transceiver; lower gate drive (80 mA) | Suitable for cost-sensitive non-AEC-Q100 applications with simpler control algorithms | Choose only for legacy 8-bit migration paths where LIN is added externally and thermal derating is acceptable |
Compared with TLE9879QXW40XUMA2, this part trades CAN FD capability for lower system cost and smaller footprint; versus MC33816AE, it delivers higher integration, faster control loop execution, and full AEC-Q100 compliance without external components.

FAQ
What is the maximum motor phase current supported by TLE9877QXW40XUMA2?
The TLE9877QXW40XUMA2 does not drive motor windings directly. It drives external N-channel MOSFETs with up to 120 mA gate current per channel. Maximum phase current depends on selected external MOSFETs, heatsinking, and PWM frequency-typical designs achieve 30 A RMS with appropriate Si MOSFETs and thermal design.
Does TLE9877QXW40XUMA2 require an external crystal oscillator?
No. The device uses an internal RC oscillator trimmed to ±1% accuracy over temperature and voltage. An external crystal is optional and only needed if system-level timing requirements exceed ±1% tolerance-e.g., for synchronous LIN/CAN coexistence or precise timestamping.
Can TLE9877QXW40XUMA2 operate without the LIN interface enabled?
Yes. The LIN transceiver circuitry can be disabled via configuration bits in the LINCON register. When disabled, LIN_TxD and LIN_RxD pins become general-purpose I/Os, and the internal LIN state machine enters low-power standby mode without affecting MCU or motor control functions.
What debug interface does TLE9877QXW40XUMA2 support?
The device supports SWD (Serial Wire Debug) via dedicated SWDIO and SWCLK pins. It is compatible with Infineon DASLink and third-party ARM Cortex-M debug probes. No JTAG support is provided; SWD offers full flash programming, real-time variable inspection, and hardware breakpoint capability.
