The A1391/2/3/5 family of linear Hall effect sensors provides a voltage output that is directly proportional to an applied magnetic field.
The A139x minimise current consumption to less than 25 μA through the addition of a user-selectable sleep mode, perfect for battery-operated applications. You can control the current consumption by applying a logic level signal to the SLEEP pin. The outputs of the devices are not valid (high-impedance mode) during sleep mode.
High-impedance output during sleep mode
Compatible with 2.5 V to 3.5 V power supplies
10 mW power consumption in the active mode
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
Preset sensitivity and offset at final test
