●A1391/2/3/5 3V Linear Hall Effect Sensors, Allegro Microsystems
●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
