MP6637

5.5V, 1.3A Peak, Three-Phase, Sensorless BLDC Motor Driver with Integrated MOSFETs

Datasheet

Description

The MP6637 is a three-phase, sensorless, brushless DC (BLDC) motor driver with integrated power MOSFETs. The device features sinusoidal sensorless control for better efficiency and low vibration, with up to 1.3A of peak phase current. The input voltage (V_CC) ranges from 2.5V to 5.5V.

The MP6637 controls the motor speed through the pulse-width modulation (PWM) signal with a 1kHz to 100kHz PWM input frequency.

The MP6637 features rotational speed detection. The rotational speed 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 MP6637 is available in an SOT583 package.
