Product details

Overview

TLE98932QTA62SXUMA1 from Infineon Technologies is a 32-bit Arm® Cortex®-M3 automotive microcontroller with integrated CAN-FD transceiver and 3-phase N-FET bridge driver, operating from 5.5 V to 28 V supply, featuring 32 KB FLASH0, 256 KB FLASH1 with EEPROM emulation, 32 KB RAM, and qualified for ASIL-B safety applications per ISO 26262. It targets BLDC motor control in automotive auxiliary drives including HVAC blowers and coolant pumps.

For engineers reviewing the TLE98932QTA62SXUMA1 datasheet, TLE98932QTA62SXUMA1 pinout, TLE98932QTA62SXUMA1 application, or TLE98932QTA62SXUMA1 equivalent, this device delivers integrated motor control with BEMF sensing, dual ADCs (12-bit + 10-bit), SDADC for rotary position, CCU7-based PWM generation, and fail-safe switch-off path - critical for compact, high-reliability automotive motor modules.

Technical Context

The TLE98932QTA62SXUMA1 integrates a dedicated Power Management Unit (PMU) with master supply (VDDP), core regulator (VDDC), and external supply (VDDEXT), enabling single-rail operation across 5.5–28 V input while maintaining stable internal voltage domains. Its System Control Unit (SCU) includes PLL-based clock generation, safe reference clock supervision, and FIFO fail-safe monitoring to support functional safety requirements.

Motor control execution relies on the Capture Compare Unit 7 (CCU7) for precise 3-phase PWM timing, synchronized with three BEMF comparators and a low-side shunt current sense amplifier (CSA). The integrated CAN-FD controller and physical transceiver (CANTRX) operate independently of the MCU core via MultiCAN+ peripheral, supporting real-time diagnostics and networked actuator coordination.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice

TLE98942QTA62SXUMA1	LQFP-64 with enhanced safety features: dual-core lockstep monitor, additional ASIL-B diagnostic coverage, extended temperature grade (−40°C to +185°C)	Required for higher-ASIL systems (e.g., brake-by-wire actuators) where fault injection testing mandates redundant monitoring paths	Select when full ASIL-B certification evidence (FMEDA, safety manual, HW-SIL analysis) is contractually required beyond SEooC baseline.

Compared with TLE98932QTA62SXUMA1, the TLE98922 offers cost and size reduction at the expense of analog precision and safety depth, while the TLE98942 adds hardware-level redundancy and extended thermal margin - making the TLE98932 the optimal balance for mid-tier automotive BLDC applications requiring integrated CAN-FD, BEMF sensing, and ASIL-B compliance without over-engineering.

FAQ

What is the maximum junction temperature rating for TLE98932QTA62SXUMA1?

The device is rated for continuous operation from −40 °C to +175 °C junction temperature, validated per AEC-Q100 Grade 0 requirements. Thermal resistance (R_θJA) is 32 K/W in standard LQFP-64 layout with 2-layer 2 oz copper and 4 thermal vias under the EP pad, enabling full-power operation at 85 °C ambient without forced airflow.

Does TLE98932QTA62SXUMA1 support sensorless BLDC commutation out of the box?

Yes - it includes three dedicated BEMF comparators with programmable hysteresis, CCU7 timer units configured for six-step commutation timing, and GPIOs mapped for Hall sensor inputs. Reference firmware for sensorless trapezoidal control is provided in Infineon's MOTIX™ BLDC SDK v3.2.1, including startup alignment and zero-crossing detection routines.

Can the integrated CAN-FD transceiver operate independently of the Arm® Cortex®-M3 core?

Yes - the CANTRX block is fully autonomous: it receives and transmits CAN frames via the MultiCAN+ peripheral without CPU intervention, supports automatic retransmission, error frame generation, and bus-off recovery. Core sleep modes (e.g., IDLE, STANDBY) preserve CAN receive functionality with wake-on-CAN capability.

Is external crystal mandatory for TLE98932QTA62SXUMA1 operation?

No - the device includes an internal RC oscillator (IRC) with ±2% accuracy for initial boot and fail-safe operation. However, for CAN-FD timing compliance (±0.5% bit rate tolerance), an external 8 MHz or 16 MHz crystal connected to XTAL1/XTAL2 is required; the IRC alone does not meet CAN FD oscillator accuracy specifications.
