The EV6642-LE-00A is an evaluation board designed to demonstrate the capabilities of the MP6642, a three-phase, sensorless brushless DC (BLDC) motor driver with integrated power MOSFETs and up to 5A of phase peak current. It features sensorless field-oriented control (FOC) for better efficiency and low vibration. The input voltage (V_IN) ranges from 5V to 35V.

The MP6642 controls the motor speed through the pulse-width modulation (PWM) signal and a 50kHz to 100kHz PWM input frequency. It also supports DC input speed control.

The MP6642 includes rotational speed detection. The rotational speed detector (FG/RD pin) is an open-drain output. The direction control is controlled via the DIR pin’s input. The I²C interface can be used to access the internal register configuration for optimized operation.

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

The MP6642 is available in a TQFN-17 (4mmx4mm) package with wettable flanks.
