3-Phase Brushless Fan Motor Driver - BM6244FS (New)

This 3-phase Brushless Fan motor driver IC adopts MOSFET as the output transistor, and put in a small full molding package with the 150°/120° commutation controller chip and 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 downsizing the built-in PCB of the motor.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
