The BM6243FS 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 PrestoMOSFET, capable of delivering an output current of up to 2.5A continuously and 4.0A in pulse mode. The device includes several protection circuits, including overcurrent protection (OCP), thermal shutdown (TSD), under-voltage lockout (UVLO), and fault signal output. It operates with a 3.3V logic input and is packaged in a compact SSOP-A54_23 format, measuring 22.0mm x 14.1mm x 2.4mm. The BM6243FS is suitable for standardizing motor units when combined with the BD6201x series controller.
This 3-phase Brushless Fan motor driver IC adopts PrestoMOS™ as the output transistor, and put in a small full molding package with the high voltage gate driver chip. The protection circuits for overcurrent, overheating, under voltage lock out and the high voltage bootstrap diode with current regulation are built-in. It provides optimum motor drive system for a wide variety of applications by the combination with controller BD6201x series and enables motor unit standardization.
