Allegro Microsystems Surface Hall Effect Sensor 2.5 V 3.5V, MLP, 6-Pin

The A1391/2/3/5 family of linear Hall effect sensors provides a voltage output that is directly proportional to an applied magnetic field.

The A139x minimise current consumption to less than 25 μA through the addition of a user-selectable sleep mode, perfect for battery-operated applications. You can control the current consumption by applying a logic level signal to the SLEEP pin. The outputs of the devices are not valid (high-impedance mode) during sleep mode.
