Provide original and genuine products MP6654 18V, Single-Phase, ESD-Enhanced, BLDC Fan Driver with Integrated Hall Sensor

Description

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) signal on the PWM pin. The device 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 the internal Hall comparator’s output. Higher speeds produce higher frequency signals.

Full protection features include input over-voltage protection (OVP), under-voltage lockout (UVLO) protection, over-current protection (OCP), locked rotor protection, and thermal shutdown.

The MP6654 is available in TSOT23-6-SL and TSOT23-6-R packages.
