Key Features  Single-phase BLDC motor with hall IC interface  PWM or voltage control input  FG/RD/ALM/RALN/RXX/RRXX output  Close loop or/and open loop control  Current limit and over-current 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  10-pin MSOP10 package MF610 is a single 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. MF610 receives motor position signal from Hall IC and can control the H -bridge 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 MF610’ s development system, it ’s much easier and adjustable for application.
