PT3621   Medium Sensitivity Switch Type Hall Sensor IC

The PT3621 is designed for magnetic actuating using a unipolar magnetic field. The built-in dynamic offset cancellation of pre-amplifier stage achieves optimal symmetrical magnetic sensing. This Hall effect IC is designed for on/off detection, especially for automotive/industrial application. PT3621 provides precious actuation to ensure safety. The supply voltage range is from 2.5V to 18V and maximum output current is 25mA.
