ET8215Q
- Description
- The ET8215 is a Three-Phase , sensorless FOC controlled DC Brushless Motor drive IC with built-in drive MOS. The chip is highly integrated with the components required for motor control, requiring fewer peripheral components, low noise, and low motor torque ripple. Built-in EEPROM, which can configure customer motor parameters, start and speed control modes. The speed control interface can select PWM, analog input, or I2C to adjust motor speed, and can output the motor speed in real time through FG pin or I2C interface. Speed control modes include constant speed, constant current and open loop mode. It has motor speed indication function, and protection modes include overcurrent, undervoltage, over temperature, stall and some other modes. The sleep current of the chip is 40uA.
