About This Product

■Summary

The MP6631A is a 3-phase brushless DC (BLDC) motor driver with integrated power MOSFET. The device accepts a single external Hall-effect sensor or triple external Hall-effect sensors to drive 3-phase BLDC motors with up to 3A peak phase current and input voltage (VIN) range of 3.6V to 35V. The MP6631A has a closed/open loop to control motor speed through a pulse width modulation (PWM) signal or a DC signal on the PWM/DC pin. The device has a built-in configurable speed curve function. It also features sinusoidal drive for maximum torque and low speed ripple and noise over the full speed range. MP6631A detects rotation speed. The rotation speed detector (FG/RD pin) is an open drain output. Outputs high or low voltage for the output of the Hall comparator. Directional control is via the DIR pin input. Extensive protection features include input overvoltage protection (OVP), undervoltage lockout (UVLO), lock-rotor protection, overcurrent protection (OCP), and thermal shutdown. MP6631A is available in a QFN-26 (3mm x 4mm) package.

■Features and benefits

・Operating input voltage (VIN) range from 3.6V to 35V ・Peak phase current up to 3A ・Integrated 160mΩ high-side MOSFET (HS-FET) and low-side MOSFET (LS-FET) ・Sine wave drive ・Supports 0V to 1.2V DC input or 1kHz to 100kHz pulse width modulation (PWM) input ・Supports differential input of triple-hole or single-hole elements ・Closed/open loop speed control ・Direction/brake input ・Power saving mode ・0.5s/4.5s lock protection ・Overcurrent protection (OCP) ・Single pulse or triple pulse FG output per electrical cycle ・FG signal: Rotation speed display ・Soft start (SS) for low noise and current overshoot ・Provided in QFN-26 (3mm x 4mm) package
