The IMD111T-6F040 from Infineon Technologies is a Three-Phase Brushless DC Motor Controller that has been designed for controlling three-phase motors. It requires an input voltage of 3 – 5.5 V and provides an output current of 375 mA. This motor driver IC consists of RAM, flash memory, an iMOTION control engine, a voltage regulator, a high-side driver and bootstrap, a low-side driver, a digital-to-analog converter, a 12-bit ADC, an analog comparator, a debugger, UART, GPIO, PWM generation and ADC sync, PWM signal conditioning, and PFC control circuitries. It utilizes thin-film silicon-on-insulator (SOI) technology that offers robustness against negative transients to ensure reliability. This DC motor driver has a motion control engine (MCE) to create a ready-to-use solution to perform control operations of a permanent magnet synchronous motor (PMSM), providing the shortest time-to-market for any motor system at the lowest system and development cost.
This motor driver IC includes an integrated script engine that adds flexibility to the application without interfering with the functionality of both the motor and power factor correction (PFC) control algorithms. It is equipped with over-current protection circuitries to prevent short-circuit-related damages. This controller IC is available in a surface-mount package that measures 9 x 9 mm and is ideal for small and major home appliances, fans, pumps, compressors, and general-purpose variable-speed drive applications.
