MPS’ MP6650 single-phase brushless DC motor driver is designed to provide advanced features for efficient motor control. The device is capable of driving single-phase brushless DC fan motors with up to 2 A of output current, making it suitable for various applications.
One key feature of the MP6650 is its wide input voltage range of 3.3 V to 18 V, allowing flexibility in different power supply configurations. The integrated input line reverse-voltage protection (RVP) helps save costs by eliminating the need for an external diode on the supply line.
The motor speed is controlled through the PWM signal on the PWM pin, enabling precise speed regulation. Additionally, the device includes a rotational speed detection feature and rotor lock fault indication on the frequency generator (FG)/rotor deadlock (RD) pin, enhancing system reliability.
To ensure optimal performance and protection, the MP6650 incorporates various safety features such as input overvoltage protection (OVP), undervoltage lockout (UVLO), RD protection, thermal shutdown, and input reverse protection. These features safeguard the motor driver and connected components from potential damage due to electrical faults or environmental conditions.
Moreover, the MP6650 implements a soft on/off phase transition and automatic phase-lock function to reduce audible noise and power loss during operation. By minimizing external component requirements, the device helps lower overall solution costs while offering high performance and reliability.
Available in compact TSOT23-6-L, TSOT23-6-R, TSOT23-6-SL, and TSOT23-6-RSL packages, the MP6650 provides designers with a versatile and cost-effective solution for motor control applications. Its advanced features and comprehensive protection mechanisms make it an ideal choice for demanding industrial and consumer electronics systems.
