The APS12450LLHALT-1SLA is a three-wire Hall-effect latch with advanced diagnostics, designed for automotive and industrial safety systems. It is packaged in a 3-pin SOT23-W surface-mount package and operates over a supply voltage range of 3 to 30 V. The device is qualified to AEC-Q100 Grade 0 and supports operation up to a 175°C junction temperature. It includes integrated diagnostics for signal path, regulator, Hall plate, bias, and overtemperature conditions, and complies with ISO 26262 as an ASIL B SEooC component. The part features a switchpoint of 50 G (typical) with zero temperature coefficient and low output polarity. It incorporates an internal voltage regulator, overvoltage clamp, reverse-battery protection, and ±8 kV HBM ESD protection.
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.
