ETC AS443

AS443
24V, 50~150G, Unlatched
Hall Effect Position Sensor
DESCRIPTION
FEATURES
The AS443 Bipolar Hall-Effect sensors are small,
„
versatile digital Hall-effect devices that are operated
Miniature construction: 3.0 mm x 4.0 mm [0.12
in x 0.16 in] plastic package
by the magnetic field from a permanent magnet or an
„
Operating Voltage: 3.5V to 24V
electromagnet, and are designed to respond to
„
Power consumption of only 5 mA max at 4.5
South poles.
Vdc for energy efficiency
A built-in regulator provides enhanced stability of
„
Unipolar magnet for single magnet applications
operation over 3.5Vdc to 24 Vdc supply voltage
„
High speed: operates from 0 kHz to over 100
range, and internal circuitry is designed to prevent
sensor damage in case the supply voltage polarity is
kHz
„
accidentally reversed.
Broad temperature range of -40 °C to 150 °C
[-40 °F to 302 °F]
The device includes an on-chip hall voltage
„
Built-in reverse polarity protection
generator for magnetic sensing, a comparator that
amplifiers the hall voltage, and a Schmitt to provide
APPLICATIONS
switching
„
hysteresis
for
noise
rejection,
and
open-collector output.

sensing
The AS443 is factory tested at 25 °C [77 °F]

Note:
*Absolute maximum ratings are the extreme limits the device is designed to withstand without damage to the device.
However, the electrical and mechanical characteristics are not guaranteed as the maximum limits (above recommended
operating conditions) are approached, nor will the device necessarily operate at absolute maximum ratings.
