The A1150, A1152, A1153, A1155, A1156, A1157, and A1158 are two-wire single-pole Hall-effect switch series that are factory-tuned for the highest magnetic switch point accuracy. These devices are manufactured using its proprietary high-frequency four-phase chopper stabilization technology through Allegro's® advanced BiCMOS wafer fabrication process. This technology achieves magnetic stability relative to all operating temperatures, eliminating the inherent offset of single-Hall device devices for harsh application environments.
The A115x series has a variety of automotive applications. Includes sensing seat track position, seat buckle presence, hood/trunk locking, and shift selector position.
Because two-wire monopole switches use one less wire than traditional open-collector switches, two-wire monopole switches are particularly suitable for cost-sensitive applications. Moreover, the system designer always has access to diagnostic information because the output current must always be within two narrow ranges. Any current level outside of these two ranges indicates a fault.
All products are available in two package types. The LH is a SOT-23W miniature low-profile package for surface mount applications. UA is a three-pin, ultra-miniature, single-in-line package (SIP) for via mounting. Both packages are lead-free and feature 100% matte tin-plated pinframes.
