Description

The EV6631B-L-00A is an evaluation board designed to demonstrate the capabilities of the MP6631B, a 3-phase brushless DC (BLDC) motor driver with integrated power MOSFETs. The MP6631B drives a 3-phase BLDC motor with 1 or 3 external Hall sensors. It can achieve a peak phase current up to 3A across the 3.6V to 35V input voltage (VIN) range.The MP6631B controls the motor speed through the pulse-width modulation (PWM) signal, or through the DC signal on the PWM/DC pin. The device provides closed-loop and open-loop control and a built-in, configurable speed curve function. The device also features a sinusoidal drive for maximum torque, as well as low speed ripple and noise across the entire speed range.
