APS11200 2 - High-Temperature Precision Hall-Effect Switch FEATURES AND BENEFITS Unipolar switchpoints ASIL A functional safety compliance Automotive-grade ruggedness and fault tolerance □□Extended AEC-Q100 qualification □□Reverse-battery and 40 V load dump protection □□Operation from –40°C to 175°C junction temperature □□High EMC immunity, ±12 kV HBM ESD □□Output short-circuit and overvoltage protection □□Superior temperature stability □□Resistant to physical stress 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 APS11200 is a three-wire, planar Hall-effect sensor integrated circuit (IC).This device was developed in accordance with ISO 26262 and supports a functional safety level ofASILA. This Hall-effect switch IC features extended AEC-Q100 qualification and is ideal for high-temperature operation up to 175°C junction temperatures. In addition, the APS11200 includes a number of features designed specifically to maximize system robustness such as reverse-battery 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...
