Allegro introduces a new family of Hall-effect switches and latches which might be extremely temperature-stable and stress-resistant sensors suited for operation around extended temperature ranges for you to 150°C. Superior high temperature overall performance is made possible via dynamic offset cancelling, reducing the residual offset voltage normally due to device over-molding, temperature dependencies, and thermal stress. Allegro’s A1220 along with A1221 devices are most commonly utilized to detect the speed and also direction of ring magnets for engine commutation. The A1120 is most commonly used to detect the end position in windsheild wiper systems and multiple discrete positions within shift selectors.

Each device includes on a single rubber chip: a voltage regulator, Hall-voltage generator, small-signal amplifier, helicopter stabilization, Schmitt trigger, and also short-circuit protected open-collector output that will sink up to 25 mA. An on-board regulator makes it possible for operation with present voltages of 3.2 to 24V. Significant advantages are usually realized by reducing the particular minimum operating existing. These devices can now be used in 3 V apps and additional external resistance can be added in collection with the supply pin number for greater security against transient situations. Two package variations provide a magnetically optimized package for most applications. Deal type LH is a modified SOT23W, surface mount package, while the UA is a three-lead, ultra-mini-SIP with regard to through-h ole mounting. Each deal type is available while lead (Pb) free (suffix, -T), which has a 100% matte tin-plated lead framework.

These new products are priced from $0.41 to $0.49 determined by package type. All devices are targeted at the automotive, industrial and consumer markets having a 12-14 week lead-time.
