A field-oriented control (FOC) algorithm is fully integrated to achieve the best efficiency and acoustic noise performance. EEPROM programmability is included to optimize motor startup performance. The motor speed is controlled by applying a duty cycle command to the PWM input. A simple I2C interface is provided for setting motor-rated voltage, rated current, rated speed, resistance, and startup profiles. The I2C interface is also used for on/off control, speed control, and speed readback. The AMT49400 is available in a very small 10-lead SOIC with exposed pad, (suffix LK).
