Description
The MP6617 is a single-phase brushless DC (BLDC) motor driver with integrated power MOSFETs and a Hall sensor. It drives a single-phase BLDC motor with up to 6A of peak current. The input voltage (VIN) ranges between 3.3V and 18V.
The MP6617 controls the motor speed through the pulse-width modulation (PWM) signal, with a PWM input frequency between 60Hz and 100kHz.
The MP6617 also has a rotational speed detection feature. 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.
Rich protections include input over-voltage protection (OVP), under-voltage lockout (UVLO), locked-rotor protection, over-current protection (OCP), and thermal shutdown protection.
The MP6617 is available in a QFN-10 (2.5mmx3mm) package.
