APS12000 Datasheet | Allegro MicroSystems

FEATURES AND BENEFITS - ASIL A functional safety pliance - Planar and vertical Hall-effect sensor ICs - 3.3 to 24 V operation - Automotive-grade ruggedness and fault tolerance - Extended AEC-Q100 qualification - Internal protection circuits enable 40 V load dump pliance - Reverse-battery protection - Output short-circuit and overvoltage protection - Operation from - 40°C to 175°C junction temperature - High EMC immunity - Symmetrical latch switch points - Choice of output polarity - Open-drain output - Solid-state reliability PACKAGES Not to scale 3-pin SOT23W (suffix LH) 3-pin SIP (suffix UA) DESCRIPTION The APS12000 and APS12060 families of Hall-effect latches are AEC-Q100 qualified for 24 V automotive applications and pliant with ISO 26262:2011 ASIL A. These sensors are temperature-stable and suited for operation over extended junction temperature ranges up to 175°C. The APS12000 and APS12060 families are available in several different magnetic sensitivities to offer flexible options for system design. They are available in active high and active low variants for ease of integration into electronic subsystems. The APS12000 features a Hall-effect element that is sensitive to magnetic flux perpendicular to the face of the IC package. The APS12060 features a vertical Hall-effect sensing element sensitive to magnetic flux parallel to the face of the IC package. The devices include on-board reverse-battery and overvoltage protection for operating directly from an automobile battery, as well as protection from shorts to ground by limiting the output current until the short is removed. The device is especially suited for operation from unregulated supplies. Continued on next page...
