Description
The MP6616A 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 MP6616A 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 MP6616A 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) protection, locked rotor protection, over-current protection (OCP), and thermal shutdown.
The MP6616A is available in a QFN-10 (2mmx3mm) package.
