OVERVIEW

The PT3611 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. This Hall effect IC is optimal for DC brushless motor application. The supply voltage range is from 3.8V to 24V and maximum output current is 50mA.
