EV6638-RPU-00A 15V, 1.7A Peak, Three-Phase Sensorless BLDC Motor Driver Evaluation Board
The EV6638-RPU-00A is an evaluation board designed to demonstrate the capabilities of the MP6638, a three-phase sensorless and brushless (BLDC) motor driver with integrated power MOSFETs. It features sinusoidal sensorless control for better efficiency and low vibration, with up to 1.7A of peak phase current. The input voltage (VIN) ranges from 2.5V to 15V.
The MP6638 controls the motor speed through the pulse-width modulation (PWM) signal with a PWM input frequency from 50Hz to 100kHz. The MP6638 also has a rotational speed detector feature. The rotational speed detector (the FG/RD pin) is an open-drain output.
Rich protection features include input overvoltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown protection.
The MP6638 is available in a UTQFN8-2mmx2.5mm package.
