Worcester, Mass.—Allegro MicroSystems Inc. has introduced an ultra sensitive, Hall-effect switch with latched digital outputs and either unipolar or omnipolar actuation.

The A1171 features operation at low supply currents and voltages, making it well-suited for battery-operated consumer and industrial electronics. Key features include lower minimum Vcc, a small, low-profile package, and push-pull complementary outputs.

The low operating supply voltage of 1.65 V to 3.5 V, and clocking algorithm assist in reducing the average operating power consumption. Power requirements are less than 15µW with a 2.75 V supply.
