APS13295 Datasheet | Allegro MicroSystems

FEATURES AND BENEFITS - Unipolar switch points - Superior ruggedness and fault tolerance - Reverse-polarity and transient protection - Operation from - 40°C to 175°C junction temperature - Output short-circuit and overvoltage protection - Superior temperature stability - Resistant to physical stress - High EMC immunity, ±12 k V HBM ESD - Operation from unregulated supplies, 2.8 to 24 V - Chopper stabilization - Solid-state reliability - Industry-standard packages and pinouts PACKAGES: Not to scale 3-pin SIP (suffix UA) 3-pin SOT23W (suffix LH) DESCRIPTION The APS13295 Hall-effect switch is a three-wire, planar Hall-effect sensor integrated circuit (IC) especially suited for operation over extended temperature ranges (up to 125°C). This Hall-effect switch IC is ideal for industrial and consumer applications and features performance enhancements permitting high-temperature operation up to 175°C junction temperatures. In addition, the APS13295 includes a number of features designed specifically to maximize system robustness such as reverse-polarity protection, output current limiter, overvoltage, and EMC protection. The single silicon chip includes: a voltage regulator, a Hall plate, small signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit-protected open-drain output. A south pole of sufficient strength turns the output on. Removal of the magnetic field- or a north pole- turns the output off. The devices include on-board transient protection for all pins, permitting operation directly from unregulated or regulated supplies from 2.8 to 24 V. Two package styles provide a choice of through-hole or surface mounting. Package type LH is a modified SOT23W, surfacemount package, while UA is a three-lead ultra-mini SIP for through-hole mounting. Both packages are lead (Pb) free and Ro Hs pliant with 100% matte-tin leadframe plating. Hall Element DYNAMIC OFFSET CANCELLATION Functional Block Diagram HALL AMP. REGULATOR SAMPLE, HOLD &...
