Product details

Overview

TLE98812QTW60XUMA1 from Infineon Technologies is a 32-bit Arm® Cortex®-M3 automotive microcontroller with integrated CAN-FD controller and transceiver, 3-phase N-FET bridge driver, and BEMF comparators-designed for brushless DC motor control in auxiliary automotive systems. It operates from 5.5 V to 28 V, supports -40°C to 175°C junction temperature, and integrates 32 KB FLASH0, 256 KB FLASH1 (with EEPROM emulation), and 32 KB RAM.

For engineers reviewing the TLE98812QTW60XUMA1 datasheet, TLE98812QTW60XUMA1 pinout, TLE98812QTW60XUMA1 application, or TLE98812QTW60XUMA1 equivalent, this device delivers integrated motor control logic, real-time current sensing via low-side shunt amplifier, 12-bit/10-bit ADCs, 14-bit SDADC for rotary position, and ASIL-B safety compliance per ISO 26262.

Technical Context

The TLE98812QTW60XUMA1 integrates a dedicated Power Management Unit (PMU) with master supply (VDDP), core regulator (VDDC), and external supply (VDDEXT), enabling single-rail operation across wide input voltage range. Its System Control Unit (SCU) provides clock generation with PLL, safe reference clock, and FIFO fail-safe supervision.

Motor control execution relies on CCU7 timer for precise PWM generation, three BEMF comparators for sensorless commutation, and a safe switch-off path that meets ASIL-B requirements. The embedded MultiCAN+ controller supports CAN-FD up to 5 Mbit/s with protocol handling and error confinement.

ASIL-B safe switch-off path	Hardware-monitored fault chain (overcurrent, overtemperature, watchdog timeout) triggers immediate gate shutdown within ≤2 µs - meets functional safety requirement without software intervention.
14-bit SDADC with differential inputs	Enables high-resolution rotor position sensing using resolver or sine/cosine encoder signals - supports field-oriented control (FOC) without external signal conditioning.
CCU7 capture-compare unit	Generates synchronized 3-phase PWM with dead-time insertion, complementary outputs, and emergency stop capability - critical for reliable BLDC commutation timing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar BLDC motor controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE9882QTW60XUMA1	Same package and pinout; adds second CAN-FD channel and enhanced SDADC resolution (16-bit).	Required for dual-bus architectures (e.g., body domain + powertrain comms) or higher-precision rotor sensing.	Select when dual CAN-FD or extended diagnostic coverage is mandatory; otherwise, TLE98812 offers optimal cost/performance balance.
MC9S12VR64MLC	Legacy 16-bit S12X core; no integrated gate drivers or CAN-FD; requires external FETs and CAN transceiver.	Suitable only for legacy redesigns where toolchain continuity outweighs performance and integration gains.	Not recommended for new designs - lacks ASIL-B support, modern motor control peripherals, and automotive longevity roadmap.

Compared with TLE9882QTW60XUMA1, the TLE98812QTW60XUMA1 trades secondary CAN-FD and extended SDADC resolution for lower unit cost and identical core motor control capability; versus MC9S12VR64MLC, it delivers full integration, safety certification, and 2× CPU performance - reducing total system BOM and validation effort.

FAQ

What is the maximum ambient temperature rating for TLE98812QTW60XUMA1 in automotive applications?

The device is qualified for junction temperature operation from -40°C to +175°C per AEC-Q100 Grade 0. Ambient temperature depends on PCB thermal design; with standard 2-layer FR4 and 2 oz copper, sustained ambient of 125°C is achievable at full load. Thermal pad soldering and heatsink attachment are recommended for continuous 175°C TJ operation.

Does TLE98812QTW60XUMA1 support sensorless BLDC commutation out of the box?

Yes - it includes three dedicated BEMF comparators with programmable hysteresis, CCU7 timers for precise PWM timing, and on-chip ADCs for current/voltage sampling. Reference firmware for sensorless trapezoidal commutation is provided in Infineon's MOTIX™ BLDC SDK, including startup alignment and zero-crossing detection routines.

Can the integrated CAN-FD transceiver operate at data rates above 1 Mbit/s?

Yes - the embedded CANTRX supports bit rates up to 5 Mbit/s in FD mode, with automatic switching between nominal and data phases. Electrical characteristics confirm dominant/recessive voltage thresholds and slew rate compliance per ISO 11898-2:2016, validated across -40°C to 150°C.

Is external crystal required for accurate motor timing, or does the device support internal RC oscillation?

An external crystal (XTAL1/XTAL2) is required for production-grade timing accuracy. The internal RC oscillator has ±2% tolerance and is only intended for boot-up or fail-safe modes. For BEMF sampling, PWM synchronization, and CAN bit timing, the SCU PLL locks to an external 4–20 MHz crystal - minimum 8 MHz recommended for CAN-FD 5 Mbit/s operation.
