Description
The A139x 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 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 the VREF pin
of the device. The output voltage of the device is not ratiometric
with respect to the SUPPLY pin.
