Infineon Technologies TLE98832QTW62SXUMA1

Overview

TLE98832QTW62SXUMA1 from Infineon Technologies is a 32-bit Arm® Cortex®-M3 automotive microcontroller with integrated 3-phase N-FET bridge driver, CAN-FD controller and transceiver, 12-bit ADC (19 channels), 14-bit SDADC for rotary sensing, BEMF comparators, and safety features compliant with ISO 26262 ASIL-B. It operates from 5.5 V to 28 V supply and supports BLDC motor control in HVAC blowers and radiator fans.

For engineers reviewing the TLE98832QTW62SXUMA1 datasheet, TLE98832QTW62SXUMA1 pinout, TLE98832QTW62SXUMA1 application, or TLE98832QTW62SXUMA1 equivalent, key selection criteria include integrated bridge driver voltage rating (28 V max), CAN-FD protocol handler latency (< 1 µs), safe switch-off path response time (≤ 2 µs), and junction temperature range (−40 °C to +175 °C).

Technical Context

The TLE98832QTW62SXUMA1 integrates a dedicated CCU7 timer unit for precise 3-phase PWM generation with dead-time insertion and synchronous modulation, coupled with hardware BEMF comparators enabling sensorless commutation without CPU intervention. Its MultiCAN+ controller supports concurrent CAN-FD frames up to 5 Mbps with configurable message objects and hardware filtering.

Power management includes a PMU with master regulator (VDDP = 5.0 V ±2%), VDDC (3.3 V ±2%) for core logic, and VDDEXT (1.2 V ±2%) for analog subsystems - all monitored by independent brown-out detectors and FIFO-based fail-safe supervision. The SDADC supports 2×2 differential inputs with 14-bit resolution and oversampling for high-accuracy rotor position estimation.

FAQ

What is the maximum ambient temperature rating for TLE98832QTW62SXUMA1 in continuous operation?

The device is qualified for junction temperature operation from −40 °C to +175 °C. Under typical automotive under-hood conditions with 4-layer PCB, 2 oz copper, and 2 cm² EPAD thermal pad, maximum ambient temperature is +125 °C at 100% load, verified per AEC-Q100 Grade 0 test conditions.

Does TLE98832QTW62SXUMA1 support sensorless BLDC commutation out-of-the-box?

Yes - it includes three dedicated BEMF comparators with programmable hysteresis, CCU7 timer hardware for synchronous PWM/BEMF sampling, and built-in dead-time control. Reference firmware for trapezoidal sensorless commutation is provided in Infineon's MOTIX™ BLDC SDK v3.2.1.

Can the integrated CAN-FD transceiver operate in standby mode with wake-on-CAN functionality?

Yes - the CANTRX block supports Sleep mode with < 30 µA quiescent current and wake-on-CAN via dominant bus activity detection. Wake event triggers internal reset and restores full CAN-FD operation within 120 µs, compliant with ISO 11898-2:2016 sleep/wake specifications.

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

The device uses an internal 12 MHz RC oscillator calibrated against an external 4–20 MHz crystal (XTAL1/XTAL2). For motor control timing, the PLL locks to the crystal input, achieving ±0.5% frequency stability over temperature and voltage - eliminating need for external TCXO while maintaining < 100 ns PWM edge jitter.
