Description
The MP6616B is a single-phase, brushless DC (BLDC) motor driver with integrated MOSFETs and an embedded Hall-effect sensor. It can drive up to 2A of continuous output current (IOUT) across a 3.3V to 18V input supply voltage (VCC) range.
The MP6616B supports both speed open-loop and closed-loop control. The speed is controlled 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 FG/RD pin can function as a rotational speed detector or rotor deadlock indicator. This pin is an open-drain output that must be pulled up externally.
Rich protection features include input over-voltage protection (OVP), under-voltage lockout (UVLO) protection, locked-rotor protection, over-current protection (OCP), and thermal shutdown.
The MP6616B is available in a QFN-10 (2mmx3mm) package.

APPLICATION
GAMING CONTROLLERS & PERIPHERALSAPPLICATIONGaming controllers and peripherals are expected to have fast, accurate controls, reliable haptic feedback, and a long battery life. The nature of these devices means they must also be lightweight, comfortable to hold, and fairly durable. Connectivity options include RF signals, WiFi, Bluetooth, and near field control (NFC), and many controllers and peripherals integrate more than one of these. Oth...
