The IMC302AF064XUMA1 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 260 mA. This motor driver IC consists of a 32-bit ARM Cortex-M0 core, RAM, flash memory, an iMOTION control engine, Universal serial interface channels (USIC) and a 12-bit analog-to-digital converter (ADC). It features a motion control engine (MCE) to create a ready-to-use solution to perform control operations of a permanent magnet synchronous motor (PMSM). This motor driver IC integrates a script engine for application control customization and includes drive and system protection features. It has a flexible space vector pulse width modulation (PWM) for sinusoidal voltage control and performs current sensing via single or leg shunt. This motor driver IC benefits from Hall sensor operation using analog or digital Hall.
This UL 60730-1-certified motor driver is equipped with a built-in temperature sensor and has over-current protection circuitries to prevent short-circuit-related damages. It supports flexible control input options such as UART, frequency, duty cycle or analog signal. This controller IC is available in a surface-mount package that measures 10 x 10 mm and is ideal for small and major home appliances, fans, pumps, compressors, and general-purpose variable-speed drive applications.
