Allegro在90V电机驱动IC中新增Cortex-M4内核Allegro adds Cortex-M4 to 90V motor driver ICs
➀ Allegro Microsystems推出搭载40MHz Arm Cortex-M4内核的独立三相汽车无刷电机驱动IC，支持高达90V电压，用于控制外部n沟道MOSFET；
➁ 该系列IC配备12位PWM、多通道ADC、串行通信及内部稳压功能，采用7x7mm QFN封装，提供60V/90V及不同存储和I/O配置的版本；
➂ Segger的调试工具已支持这些芯片，Allegro此前于2025年4月发布了不带MCU的电机驱动器和传感器。
➀ Allegro Microsystems launched standalone three-phase automotive brushless motor driver ICs with a 40MHz Arm Cortex-M4 core, supporting up to 90V rails and targeting external n-channel MOSFET control;
➁ The ICs feature 12-bit PWM, multiple ADCs, serial communication, and internal voltage regulation, available in 7x7mm QFN packages with variants for 60V/90V and different flash/I/O configurations;
➂ Debugging tools from Segger now support these ICs, and Allegro previously released non-MCU motor drivers and sensors in April 2025.
