The APS12450 is a three-wire Hall-effect latch with integrated diagnostics, designed for automotive and industrial safety systems. It is qualified to AEC-Q100 Grade 0 and operates up to a 175°C junction temperature with a 3 to 30 V supply range. The device features ASIL B SEooC compliance per ISO 26262, continuous background diagnostics, overvoltage and reverse-battery protection, and an internal voltage regulator. It is available in a 3-pin SOT23-W surface-mount package (suffix LH) with a 13-inch reel packing option, and includes a magnetic switchpoint of 150 G (typical) and a 0%/°C temperature coefficient. The output polarity is low (output on for positive magnetic flux).
The APS12450 offers enhanced functional safety with advanced diagnostics, a fault state output, and continuous background diagnostics for reliable operation in automotive and industrial applications.
