PT3601A – General purpose Hall-effect Latch

The PT3601A 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 fan application . The supply voltage range is from 2.5V to 18V and the maximum output current is 25mA.
