MP6616GD Datasheet | Monolithic Power Systems

DESCRIPTION The MP6616 is a single-phase brushless DC motor driver with integrated power MOSFETs and Hall Effect Sensor. It drives single-phase brushless DC motor motors, with up to 2A operation output current. The input voltage ranges from 3.3V to 18V. The MP6616 controls the motor speed through the PWM signal on PWM pin with close loop control, built-in programmable speed curve function. It features programmable soft on/off phase transition and Hall angle trimming over full speed range which can flexibly optimize low speed and high speed performance. The MP6616 also has the rotational speed detector feature . The rotational speed detector (the FG pin) is the output of an open drain collector. It outputs a high or low voltage relative to the internal Hall parator’s output. In addition direction control is also achieved through DIR pin input. Rich protection includes input over-voltage protection, under-voltage Lockout, locked-rotor protection, over-current protection, and thermal shutdown protection. The MP6616 is available in a QFN10-2x3mm package.
