GND/DC ground . an B High sensitivity & low The PT3935 is designed for magnetic actuating using a bipolar thermal drift magnetic magnetic field. The built-in dynamic offset cancellation of pre-amplifier sensing stage achieves optimal symmetrical magnetic sensing. The output @ Low power consumption driver provides a linear drive to eliminate switching noise. This motor & high driving efficiency driver IC is especially designed for OA cooling fan solution or industry equipments such as inverters or fan trays. PT3935 also provides RD signal for revolution detection. The supply voltage range is from 4.5V to 30V.
