Description
A1391, A1392, A1393, and A1395 Micropower 3 V Linear Hall-Effect Sensor ICs with Tri-State Output and User-Selectable Sleep Mode .
The A139x family of linear Hall-effect sensor integrated circuits (ICs) provide a voltage output that is directly proportional to an applied magnetic.
Features
* ▪ 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
sens
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 ap
