ROHM Semiconductor USA, LLC Motor Drivers, Controllers BM6249FS-E2

The BM6249FS-E2 is a 3-phase brushless fan motor driver IC designed for applications such as air conditioners, air purifiers, water pumps, dishwashers, and washing machines. It features a built-in 600V PrestoMOS,Ñ¢ output transistor and supports an output current of 2.5A, with a maximum pulse current of 4.0A. The device incorporates a 180¬8 sinusoidal commutation logic and PWM control for upper and lower arm switching, allowing for precise phase control from 0¬8 to +40¬8 in 1¬8 increments. Protection circuits are integrated to safeguard against overcurrent, overheating, and under-voltage lockout, enhancing reliability in operation. The BM6249FS-E2 also includes a fault output, FG signal output with selectable pulse numbers (4 or 12), and a regulator output of 5V at 30mA. The package dimensions are 22.0mm x 14.1mm x 2.4mm, making it suitable for compact PCB designs. This product is ideal for engineers looking for a robust and efficient motor driver solution for various household and industrial applications.
