Key Features  3-Phase brushless DC motor with hall IC interface  PWM or voltage control input  FG/RD/ALM/RALN/RXX/RRXX output  Alarm output  Reverse brake control  Software hall degree forward and backward  Close loop or/and open loop control  Current limit and over-current protection  Under voltage lock out protection  Over voltage lock out protection  Soft-start, lock-protect and auto-restart  System protection - Low-voltage detection with reset - Illegal opcode detection with reset  MTP Programming - Support 6-wire factory programming mode - Support 4-wire in-system programming mode  DC Fan Applications - Operating voltage range: 3.5V~5.5V - Operating temperature range: -40°C~105°C  16-pin SSOP16 package MF616 is a 3 -phase BLDC motor controller based on 8- bit 8 -FPPA MCU which can be programmed by 6-wire factory mode or 4- wire ISP mode. MF616 receives motor position signal from Hall IC and can control the six step square wave flexibly to make the best efficiency of the motor. Through the PADAUK patented AP development system, it can easily set any speed curve, output signal and protection parameters etc., and it can observe the motor response online immediately. Using the MF616’s development system, it’s much easier and adjustable for application.
