Infineon Technologies TLE98932QTA62XUMA1

Overview

TLE98932QTA62XUMA1 from Infineon Technologies is a 32-bit Arm® Cortex®-M3 automotive microcontroller with integrated CAN-FD transceiver and 3-phase N-FET bridge driver, designed for brushless DC motor control. It operates from 5.5 V to 28 V, features 32 KB FLASH0 + 256 KB FLASH1 (with EEPROM emulation), 32 KB RAM, -40°C to 175°C junction temperature, and ASIL-B safety compliance per ISO 26262.

For engineers reviewing the TLE98932QTA62XUMA1 datasheet, TLE98932QTA62XUMA1 pinout, TLE98932QTA62XUMA1 application, or TLE98932QTA62XUMA1 equivalent, this device supports real-time BEMF sensing via three comparators, high-precision rotor position measurement using a 14-bit SDADC with differential inputs, and safe switch-off path implementation for fault-tolerant BLDC drive systems.

Technical Context

The TLE98932QTA62XUMA1 integrates a dedicated CCU7 capture-compare unit for PWM generation and commutation timing, coupled with hardware-accelerated motor control peripherals including BEMF comparators, low-side shunt current sense amplifier, and sigma-delta ADC for sensorless or sensored rotor position tracking. Its MultiCAN+ controller supports both classical CAN and CAN-FD up to 5 Mbit/s with flexible message filtering and FIFO-based transmission.

Power management includes a multi-rail PMU generating VDDP (1.2 V core), VDDC (3.3 V I/O), and VDDEXT (5 V external interface) from a single wide-input supply. The safe switch-off path provides hardware-enforced shutdown of all six N-FET gate drivers upon fault detection, independent of software execution state.

FAQ

What is the maximum operating voltage for TLE98932QTA62XUMA1?

The device supports a single-supply input range from 5.5 V to 28 V, making it compatible with both 12 V and 24 V automotive battery systems. Absolute maximum rating is 30 V for transient conditions per AEC-Q100 stress testing, but sustained operation above 28 V is not permitted.

Does TLE98932QTA62XUMA1 include an integrated CAN transceiver?

Yes, it integrates a fully compliant CAN-FD physical layer transceiver (CANTRX) supporting data rates up to 5 Mbit/s. The transceiver meets ISO 11898-2 and ISO 11898-5 requirements and includes bus wake-up, fault protection, and common-mode noise rejection circuitry.

Can TLE98932QTA62XUMA1 operate without external gate drivers?

Yes-it contains a complete 3-phase N-FET bridge driver with integrated charge pump, high- and low-side gate outputs, and safe switch-off logic. External gate drivers are unnecessary unless driving >100 A motors or requiring specialized dead-time control outside the chip's CCU7 capabilities.

Is the SDADC in TLE98932QTA62XUMA1 suitable for resolver interface?

Yes-the 14-bit sigma-delta ADC has two differential input pairs with programmable gain and filtering, optimized for decoding resolver sine/cosine signals. It supports synchronous sampling and built-in angle calculation via hardware acceleration in the SCU block.
