A1391, A1392, A1393, and A1395 Micro Power 3 V Linear Hall Effect Sensor ICs withTri-State Output and User-Selectable Sleep Mode Features and Benefits ▪ High-impedance output during sleep mode ▪ Compatible with 2.5 to 3.5 V power supplies ▪ 10 mW power consumption in the active mode ▪ Miniature MLP/DFN package ▪ Ratiometric output scales with the ratiometric supply reference voltage (VREF pin) ▪ Temperature-stable quiescent output voltage and sensitivity ▪ Wide ambient temperature range: –20°C to 85°C ▪ ESD protection greater than 3 kV ▪ Solid-state reliability ▪ Preset sensitivity and offset at final test Package: 6 pin MLP/DFN (suffix EH) Description TheA139x family of linear Hall effect sensor integrated circuits (ICs) provide a voltage output that is directly proportional to an applied magnetic field. Before amplification, the sensitivity of typical Hall effect ICs (measured in mV/G) is directly proportional to the current flowing through the Hall effect transducer element inside the ICs. In many applications, it is difficult to achieve sufficient sensitivity levels with a Hall effect sensor IC without consuming more than 3 mA of current. The A139x minimize current consumption to less than 25 μA through the addition of a user-selectable sleep mode. This makes these devices perfect for battery-operated applications such as: cellular phones, digital cameras, and portable tools. End users can control the current consumption of the A139x by applying a logic level signal to ...
