1 / 15 page 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 theA139x by applying a logic level signal to the S¯¯L¯¯E¯¯E¯¯P¯ pin. The outputs of the devices are not valid (high-impedance mode) during sleep mode. The high-impedance output feature allows the connection of multiple A139x Hall effect devices to a single A-to-D converter input. The quiescent output voltage of these devices is 50 % nominal of the ratiometric supply reference voltage applied to theVREF pin of the device. The output voltage of the device is not ratiometric with respect to the SUPPLY pin. 1391-DS, Rev. 7 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 Micro Power 3 V Linear Hall Effect Sensor ICs withTri-State Output and User-Selectable Sleep Mode Continued on the next page… Package: 6 pin MLP/DFN (suffix EH) Functional Block Diagram Approximate scale A1391, A1392, A1393, and A1395 Amp Out VCC OUT GND Gain Offset Hall Element Regulator Programming Logic Circuit Reference Current To all subcircuits RRatio / 2 RRatio / 2 VREF SLEEP |
