The EV6637A-TL-00A evaluation board is designed to evaluate the performance of the MP6637A, a three-phase, sensorless, brushless DC (BLDC) motor driver with integrated power MOSFETs. It features sinusoidal sensorless drive for better efficiency and low vibration, with up to 1.3A of peak phase current. The input voltage (V_IN) ranges from 2.5V to 5.5V.

The MP6637A controls the motor speed through the pulse-width modulation (PWM) signal with a 1kHz to 100kHz PWM input frequency. The device also features a rotational speed detector. The rotational speed detector is an open-drain output via the FG/RD pin.

Rich protection features include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown.

The MP6637A is available in an SOT583 package.
