MP6651
MP6651 is Single-Phase BLDC Driver manufactured by Monolithic Power Systems.
DESCRIPTION
The MP6651 is a single-phase brushless DC (BLDC) motor driver with integrated power MOSFETs and a Hall-effect sensor. The input voltage (VIN) is between 3.3V and 18V.
The motor speed is controlled by the input PWM duty from PWM pin. The MP6651 Features a configurable soft-on/off mutation. It also Features a Hall offset angle across the full speed range to flexibly optimize low-speed and high-speed performance.
The MP6651 provides rotational speed detection. The rotational speed detector (the FG/RD pin) is an open-drain output. It outputs a high or low voltage relative to the internal Hall parator’s output. The FG/RD pin can also configured for rotor lock indication.
Robust protections include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked rotor protection, over-current protection (OCP), and thermal shutdown protection.
The MP6651 is available in a straight-lead SOIC-8 package and a QFN-10 (2mmx3mm) package.
