The IC households combine important parts akin to gate drivers, microcontrollers, communication interfaces, and energy provide right into a single chip, providing a minimized footprint and enhanced efficiency.
Infineon Applied sciences have launched the TLE988x and TLE989x households extending the corporate’s portfolio of MOTIX microcontroller unit (MCU) embedded energy ICs. The corporate claims that these merchandise have been designed with a minimized footprint, combining important elements akin to gate driver, microcontroller, communication interface, and energy provide all on a single chip. By integrating these options, the households present an enhancement in efficiency, providing a streamlined resolution for numerous purposes. These AEC Q-100-qualified ICs are appropriate for automotive brushed DC and brushless DC motor management purposes in physique, consolation, and thermal administration. The IC households provide quick, sturdy communication and excessive computing efficiency. Working at 60 MHz with twin flash, they embrace read-while-write performance.
The motive force household helps as much as 256 kB flash and 175°C, and options Adaptive MOSFET Management, with an algorithm that optimizes electromagnetic induction (EMI) and energy, making certain constant switching. The embedded energy ICs are backed by a complete ecosystem, together with software program and a 150 W coolant pump reference design. The corporate additionally affords Automotive Software program Course of Enchancment Functionality dEtermination (ASPICE) certified motor management libraries and business software program to simplify design and analysis.
The important thing specs of the embedded ICs embrace:
- Single energy provide from 5.5 V to twenty-eight V
- 32-bit Arm Cortex -M3 core at as much as 60 MHz
- Temperature Vary TJ: -40°C as much as 175°C
- FLASH0 as much as 32 KB, FLASH1 as much as 256 KB with EEPROM emulation
- RAM as much as 32 KB
- 3-phase bridge driver with cost pump
- Protected switch-off path
“The brand new MOTIX MCU embedded energy IC households deal with our clients’ wants for the smallest built-in good motor management options with quick and really sturdy on-chip CAN FD transceivers for host communication; the brand new product households moreover provide roughly 60 p.c extra processing energy in comparison with predecessor household and supply purposeful security and cybersecurity capabilities which have gotten more and more necessary for oil pumps in thermal administration techniques in electrical automobiles,” stated Andreas Doll, Senior Vice President and Common Supervisor Sensible Energy at Infineon.
