Product details

Overview

TLE98912QTW60XUMA1 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 BLDC motor control in auxiliary automotive systems. It operates from 5.5 V to 28 V, features 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.

For engineers reviewing the TLE98912QTW60XUMA1 datasheet, TLE98912QTW60XUMA1 pinout, TLE98912QTW60XUMA1 application, or TLE98912QTW60XUMA1 equivalent, key selection criteria include integrated motor control peripherals (CCU7 PWM, BEMF comparators, SDADC), on-chip power management (VDDP/VDDC regulators), and functional safety architecture including safe switch-off path and FIFO fail-safe supervision.

Technical Context

The TLE98912QTW60XUMA1 integrates a dedicated motor control subsystem comprising CCU7 for 3-phase PWM generation, three BEMF comparators for sensorless commutation, and a 14-bit sigma-delta ADC with 2×2 differential inputs optimized for rotary position sensing. Its MultiCAN+ controller supports CAN-FD up to 5 Mbit/s with protocol handling and error confinement.

Power delivery is managed by an internal PMU with independent VDDP (3.3 V ±5%), VDDC (1.2 V ±5%), and VDDEXT (5 V ±5%) regulators, all derived from a single 5.5–28 V supply. The safe switch-off path provides hardware-enforced shutdown of the N-FET bridge upon fault detection, meeting ASIL-B requirements without external supervision.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE98922QTW60XUMA1	Same die, LQFP-64 package, but with 32 KB FLASH0 + 256 KB FLASH1 and identical peripheral set - differs only in flash partitioning and bootloader configuration.	Supports dual-bank firmware update and secure boot with larger protected boot section; suitable for OTA-capable modules.	Select when field-upgradable firmware integrity and rollback protection are required beyond baseline TLE98912 functionality.
TLE98822QTW60XUMA1	Same package and pinout, but lacks CAN-FD transceiver and SDADC; retains CCU7, BEMF comparators, and 12-bit ADC - lower cost, reduced feature set.	Targeted at cost-sensitive non-networked applications like seat adjusters or window lifters where CAN is unnecessary.	Choose when CAN-FD and high-resolution rotary sensing are not required, and BOM cost reduction is prioritized over future network scalability.

Compared with TLE98912QTW60XUMA1, the TLE98922 offers enhanced firmware security infrastructure without sacrificing motor control capability, while the TLE98822 trades CAN-FD and SDADC for lower unit cost - making the TLE98912 the optimal balance of integrated networking, precision sensing, and ASIL-B safety for mid-tier automotive BLDC drives.

FAQ

What is the maximum operating junction temperature for TLE98912QTW60XUMA1?

The TLE98912QTW60XUMA1 is qualified for continuous operation at a junction temperature of −40°C to +175°C, validated per AEC-Q100 Grade 0 requirements. This rating enables direct mounting near high-heat sources such as BLDC motor housings in engine compartments without external heatsinking in most airflow-constrained applications.

Does TLE98912QTW60XUMA1 require external gate resistors for the N-FET bridge drivers?

No external gate resistors are required for normal operation, as the internal high-side and low-side drivers incorporate programmable slew-rate control and current-limited output stages. However, external 10 Ω resistors are recommended on HS1–HS3 outputs for EMI suppression in high-dV/dt switching environments above 20 kHz.

Can the SDADC be used simultaneously with the 12-bit ADC for multi-sensor acquisition?

Yes - the 14-bit sigma-delta ADC and 12-bit SAR ADC operate independently with separate clock domains and trigger sources. Concurrent sampling is supported via hardware synchronization using CCU7 timers, enabling simultaneous rotor position (SDADC) and phase current (12-bit ADC) capture within a single control cycle.

Is the CAN-FD transceiver compliant with ISO 11898-2:2016?

Yes, the integrated CANTRX block meets ISO 11898-2:2016 physical layer specifications, including common-mode voltage range (−2 V to +7 V), bus fault protection (±40 V), and dominant timeout functionality. It supports both classical CAN and CAN-FD data rates up to 5 Mbit/s without external components.
