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 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 theVREF pin
of the device. The output voltage of the device is not ratiometric
with respect to the SUPPLY pin.

Micro Power 3 V Linear Hall Effect Sensor ICs
with Tri-State Output and User Selectable Sleep Mode
Description (continued)
Despite the low power consumption of the circuitry in the A139x,
the features required to produce a highly-accurate linear Hall effect
IC have not been compromised. Each BiCMOS monolithic circuit
integrates a Hall element, improved temperature-compensating
circuitry to reduce the intrinsic sensitivity drift of the Hall element,
a small-signal high-gain amplifier, and proprietary dynamic
offset cancellation circuits. End of line, post-packaging, factory
programming allows precise control of device sensitivity and
offset.
These devices are available in a small 2.0 × 3.0 mm, 0.75 mm nominal
height microleaded package (MLP/DFN). It is Pb (lead) free, with
100% matte tin leadframe plating.
