Description
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 (IOUT) across a 3.3V to 18V input voltage (VIN) 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 RDS(ON) (total of 100mΩ for HS + LS) for high efficiency
- Closed-loop control without a microcontroller (MCU)
- Digital, configurable speed curve
