APS13290 and APS13291 Precision Hall-Effect Latches for Consumer and Industrial Applications FEATURES AND BENEFITS DESCRIPTION Symmetrical latch switchpoints The APS13290 and APS13291 are three-wire, planar Hall-effect Superior ruggedness and fault tolerance sensor integrated circuits (ICs) especially suited for operation Reverse-polarity and transient protection over extended temperature ranges (up to 125C). Operation from 40C to 175C junction temperature This family of precision Hall-effect latch ICs are ideal for Output short-circuit and overvoltage protection industrial and consumer applications and feature performance Superior temperature stability enhancements permitting high-temperature operation up to Resistant to physical stress 175C junction temperatures. In addition, the APS13290/1 High EMC immunity, 12 kV HBM ESD include a number of features designed specifically to maximize Operation from unregulated supplies, 2.8 to 24 V system robustness, such as reverse-polarity protection, output Chopper stabilization current limiter, overvoltage, and EMC protection. Solid-state reliability Industry-standard packages and pinouts 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 pole of sufficient strength is necessary to turn the output off. PACKAGES: The devices include on-board transient protection for all pins, Not to scale permitting operation directly from a vehicle battery or regulator 3-pin SIP with supply voltages from 2.8 to 24 V. (suffix UA) Two package styles provide a choice of through-hole or surface mounting. Package type LH is a modified 3-pin SOT23W surface-mount package, while UA is a three-pin ultramini SIP for through-hole mounting. Both packages are lead (Pb) free 3-pin SOT23W and RoHS compliant, with 100% matte-tin-plated leadframes.
