A1391SEHLT-T

The A1391SEHLT-T is a micro-power Linear Hall-Effect Sensor with tri-state output and user-selectable sleep mode. IC provides a voltage output that is directly proportional to an applied magnetic field. Before amplification, the sensitivity of typical hall effect IC is directly proportional to the current flowing through the hall effect transducer element inside the ICs. The high-impedance output feature allows the connection of multiple A139x hall effect devices to a single A-to-D converter input.

• High-impedance output during sleep mode
• 10mW Power consumption in the active mode
• Ratiometric output scales with the ratiometric supply reference voltage (VREF pin)
• Temperature-stable quiescent output voltage and sensitivity
• ESD protection greater than 3kV
• Solid-state reliability
• Preset sensitivity and offset at final test
