Worcester, MA – May 7, 2008 — Allegro® introduces a new ultra sensitive, Hall-effect switch with latched digital outputs and omnipolar magnetic actuation. It features operation at low supply currents and voltages, making it ideal for battery-operated electronics. The low operating supply voltage, 1.65 V to 3.5 V, and unique clocking algorithm assist in reducing the average operating power consumption. For example, the power requirements are less than 15 mW with a 2.75 V supply. A1172

Unlike many Hall-effect switches, both north and south polarity magnetic fields of sufficient strength activate output switching, to either off or on. Additionally, Allegro’s A1172, available in a four-pin wafer level chip scale package, provides two push-pull outputs. These outputs are configured such that one output switches off in the absence of sufficient magnetic field while the other output switches on in the absence of a magnetic field.

This polarity-independence, as well as the minimal power requirements, allows the A1172 to easily replace reed switches, providing superior reliability and ease of manufacturing while eliminating the requirement for signal conditioning.

Allegro’s A1172 device is targeted at the consumer market and is available in a four-pin wafer level chip scale package (CG).
