Infineon Technologies TLE98932QTW62SXUMA1

Overview

TLE98932QTW62SXUMA1 from Infineon Technologies is a 32-bit Arm® Cortex®-M3 automotive microcontroller with integrated CAN-FD controller, transceiver, and 3-phase N-FET bridge driver for BLDC 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 range, and ASIL-B safety compliance per ISO 26262. Used in automotive auxiliary drives including HVAC blowers and coolant pumps.

For engineers reviewing the TLE98932QTW62SXUMA1 datasheet, TLE98932QTW62SXUMA1 pinout, TLE98932QTW62SXUMA1 application, or TLE98932QTW62SXUMA1 equivalent, key selection criteria include integrated CAN-FD physical layer, on-chip BEMF comparators, 14-bit SDADC for rotary position sensing, safe switch-off path for motor fault handling, and qualification per AEC-Q100 Grade 0.

Technical Context

The TLE98932QTW62SXUMA1 integrates a dedicated 3-phase bridge driver with charge pump, CCU7-based PWM generation, and hardware-safe switch-off logic that meets ASIL-B requirements. Its analog subsystem includes three BEMF comparators, a low-side shunt current sense amplifier, dual ADCs (12-bit with 19 inputs, 10-bit with 14 inputs), and a 14-bit sigma-delta ADC with two differential pairs for high-precision rotor position measurement.

Communication is handled by one CAN-FD protocol handler with integrated transceiver, two UARTs (LIN-capable), and two synchronous serial interfaces (SSC). The MCU core runs at up to 60 MHz, supported by PMU-supplied rails: VDDP (3.3 V), VDDC (1.2 V), and VDDEXT (external 5 V or 3.3 V), all monitored and supervised via FIFO fail-safe supervision and system watchdog (SYSWDT).

FAQ

What is the maximum ambient temperature rating for TLE98932QTW62SXUMA1 in automotive applications?

The device is qualified for junction temperatures from -40°C to +175°C per AEC-Q100 Grade 0. When mounted on a standard 2-layer PCB with 2 oz copper and thermal vias to internal ground planes, it supports ambient temperatures up to +125°C in typical under-hood environments - verified via thermal simulation and board-level testing per JEDEC JESD51-2.

Does TLE98932QTW62SXUMA1 support sensorless commutation without external components?

Yes. It integrates three dedicated BEMF comparators, a low-side shunt current sense amplifier with programmable gain, and hardware-accelerated commutation logic in the CCU7 unit - enabling robust sensorless trapezoidal and FOC control without external op-amps, comparators, or ADC signal conditioning circuits.

How is functional safety implemented for the bridge driver in TLE98932QTW62SXUMA1?

Functional safety is enforced via a hardware-safe switch-off path independent of the CPU: analog monitors detect overcurrent (via CSA), overtemperature (via on-die sensor), and watchdog timeout, then directly force all six gate drivers into high-impedance safe state within <1 µs - certified as SEooC for ASIL-B per ISO 26262 Part 10.

Can TLE98932QTW62SXUMA1 operate with a 12 MHz crystal, and what clock options does it support?

Yes. The device supports external crystals from 4 MHz to 20 MHz on XTAL1/XTAL2. With a 12 MHz crystal, the internal PLL generates a stable 60 MHz system clock. It also supports external clock input, RC oscillator fallback, and safe reference clock monitoring - all configurable via SCU registers per application timing requirements.
