MP6654 Datasheet (MPS) - BLDC Fan Driver

MP6654, BLDC Fan Driver

The MP6654 is a single-phase brushless DC (BLDC) fan driver with integrated power MOSFETs and a Hall-effect sensor.

It can achieve up to 1A of peak current (IPEAK) across a wide 3V to 18V input voltage (VIN) range.

The MP6654 controls the rotational speed through the pulse-width modulation (PWM) sig

MP6654 Features

* a built-in, configurable curve speed function that is ideal for cooling fan applications, which require flexible speed curve control. The MP6654 provides rotational speed detection. The rotational speed detector (the FG/RD pin) is an open-drain output. It outputs a high or low voltage relative to th
