Features and Benefits
These 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 A1391 and A1392 minimize current consumption to less than
25
μ
A through the addition of a user-selectable sleep mode. This makes these devices per-
fect for battery-operated applications such as: cellular phones, digital cameras, and portable
tools. End users can control the current consumption of the A1391 and A1392 by applying
a logic level signal to the
ˉ ˉ ˉ ˉ ˉ pin. The outputs of the devices are not valid (high-imped-
ance mode) during sleep mode. The high-impedance output feature allows the connection of
multiple A1391 and A1392 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.
Despite the low power consumption of the circuitry in the A1391 and A1392, 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-com-
pensating 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.
This device is available in a small 2.0 × 3.0 mm, 0.75 mm nominal height micro leaded pack-
age (MLP). It is Pb (lead) free, with 100 % matte tin leadframe plating.
