MP6637A

MP6637A

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

Datasheet

Description

The MP6637A is 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_CC) ranges from 2.5V to 5.5V.

The MP6637A controls the motor speed via a pulse-width modulation (PWM) signal with a 1kHz to 100kHz PWM input frequency. The device also features rotational speed detection. The FG/RD pin outputs a pulse signal, and the pulse signal’s frequency indicates the fan speed.

Rich protection features include short-circuit protection (SCP), 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.
