Infineon's MOTIX TLE989x MCUs Offer a Single Chip, Power IC+CAN (FD) for Automotive/BLDC Motor Control, Now at Mouser
September 27, 2023 – Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components™, is now stocking the MOTIX™ TLE989x microcontrollers (MCUs) from Infineon Technologies. Expanding upon the company's already comprehensive and proven portfolio of MOTIX™ MCU embedded power ICs, the TLE989x family of MCUs features a CAN (FD) communication interface and offers roughly 60 percent more processing power compared to the TLE987x product family while providing additional functional safety and cybersecurity capabilities such as secure boot and key storage. Using a minimal footprint, these MCUs integrate a gate driver, MCU, communication interface and power supply all on a single chip, enabling an unbeatable level of integration and system cost for a variety of automotive and smart 3-phase BLDC motor control applications.
The Infineon Technologies MOTIX™ TLE989x MCUs, available from Mouser Electronics, are a perfect fit for designers looking for high-efficiency motor control functionality with embedded control and communication support in a single device. The TLE989x's motor driver is designed to operate a 3-phase motor with six external power NFETs. The MCU combines a 60 MHz Arm® Cortex®-M3 core, enabling advanced motor control algorithms, such as field-oriented control, and features six fully integrated NFET drivers optimized for driving the motor with a charge pump that supports low-voltage operation. A safe switch off the path for the bridge driver provides a fail-safe mechanism to turn off the motor and safely handle errors, satisfying ISO26262 and ASIL-B requirements. The device offers programmable current and current slope control for optimized EMC performance, and the on-chip peripherals include a current sensor, a successive approximation ADC synchronized with the capture and compare unit for PWM control, 8/16 GPIOs, three BEMF comparators and twelve 16-bit timers. The integrated CAN (FD) transceiver and MULTICAN+ controller support CAN (FD) protocol communications up to 2 Mbps.
The Infineon MOTIX TLE989x MCUs are housed in ultra-compact TQFP-48 and LQFP-64 packages with a wide -40°C to +175°C operating temperature range. The devices are supported by an evaluation board (TLE989X EVALB_TQFP), which is also available to order from Mouser. The evaluation board features sockets for both package variants, and every pin of the IC is connectable via rows of pin headers. The board is ready to be connected to a car supply and offers a USB port for the on-board SWD debugger.
