PT3906   12V All-in-One Double Coil Smart DC Fan IC with FG output

The PT3906T is designed for magnetic actuating using a bipolar magnetic field. The built-in dynamic offset cancellation of pre-amplifier stage achieves optimal symmetrical magnetic sensing. The output driver provides a linear drive to eliminate switching noise. This Hal driver IC is optimal for 12V brushless DC fan of consumer/household/ audio field. The supply voltage range is from 3V to 18V.
