MP6616

The MP6616 is a single-phase brushless DC (BLDC) motor driver with an embedded Hall-effect sensor and integrated power MOSFETs. It can achieve up to 2A of output current (I_OUT) across a 3.3V to 18V input voltage (V_IN) range.

The MP6616 controls the motor speed with closed-loop or open-loop control via the pulse-width modulation (PWM) signal on the PWM pin. The device features a configurable soft commutation angle and Hall offset angle. The Hall offset angle can be flexibly optimized for low-speed and high-speed performance across the full speed range. The MP6616 also features a rotational speed detector (the FG/RD pin). FG/RD is an open drain that outputs a high or low voltage relative to the internal Hall comparator’s output.

Protection features include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked rotor protection, over-current protection (OCP), and thermal shutdown. The MP6616 is available in a QFN-10 (2mmx3mm) package.

Advantages include:

• Fewer external components with integrated power MOSFETs and Hall sensor
• Low R_DS(ON) (total of 100mΩ for HS + LS) for high efficiency
• Closed-loop control without a microcontroller (MCU)
• Digital, configurable speed curve
