The A1308 and A1309 are linear Hall-effect sensor ICs with analog output designed for high-accuracy position sensing in automotive and industrial applications. The part is available in a 3-pin SOT-23W surface-mount package measuring 2 mm × 3 mm × 1 mm. It operates from a 5 V supply with an ambient temperature range of -40°C to 150°C, and is AEC-Q100 qualified. The device features a forward polarity output sensitivity of 2.5 mV/G, a temperature-stable quiescent voltage output, and includes output voltage clamps and undervoltage lockout for enhanced diagnostics. Thermal resistance for the SOT-23W package is 110 °C/W on a 2-layer PCB with thermal vias.
