MP6651 - Single-Phase BLDC Driver

General 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.

Key Features

  • a configurable soft-on/off commutation. 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 comparator’s output. The FG/RD pin can also configured for rotor lock indication. Robust protections include input over-voltage protection (OVP), under-vo.
