概要
The MP6652B is a single-phase brushless DC (BLDC) motor driver with integrated power MOSFETs and a Hall-effect sensor. It drives a single-phase brushless DC fan motor with up to 1.3A of peak output current (IOUT). The input voltage (VCC) ranges from 3V to 18V.
The device 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 MP6652B 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 protections include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, and thermal shutdown.
The MP6652B is available in TSOT23-6-L and TSOT23-6-SL packages.
