Product Overview

The Allegro A1101-A1104 and A1106 Hall-effect switches are advanced BiCMOS technology devices designed as replacements for the 312x and 314x lines. They offer fast power-on times, low-noise operation, and high switchpoint accuracy due to post-packaging programming. Featuring unique Hall element geometries and low-offset amplifiers, these switches minimize noise and residual offset voltage. Integrated components include a voltage regulator, Hall-voltage generator, amplifier, Schmitt trigger, and NMOS output transistor, enabling operation from 3.8 to 24 V. Extensive on-board protection allows for a 30 V absolute maximum voltage rating, suitable for automotive and industrial motor commutation without external components. Devices vary primarily in magnetic switchpoint levels and are available in ultrasmall, magnetically optimized packages like SOT23W (LH) and SIP (UA). All packages are lead-free with matte-tin plating.
