APS13291

APS13290 and APS13291 Precision Hall-Effect Latches for Consumer and Industrial Applications FEATURES AND BENEFITS Symmetrical latch 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 kV 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 SOT23W (suffix LH) 3-pin SIP (suffix UA) DESCRIPTION TheAPS13290 andAPS13291 are three-wire, planar Hall-effect sensor integrated circuits (ICs) especially suited for operation over extended temperature ranges (up to 125°C). This family of precision Hall-effect latch ICs are ideal for industrial and consumer applications and feature performance enhancements permitting high-temperature operation up to 175°C junction temperatures. In addition, the APS13290/1 include 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; a north pol...
