Continuing its leadership in magnetic
rotary encoder ICs, austriamicrosystems
introduces the AS5045, a 12-bit resolution
device, as part of its expanding family
of magnetic rotary encoder standard ICs.
The device provides absolute angle information
in a digital format, and targets motion
sensing applications in the industrial and
automotive markets where a resolution below
0.1 degree of angle is required.
“There is a variety of motion sensing
applications, where a minimum 12-bit resolution
at low rotational speeds is required, such
as torque measurement. The AS5045 addresses
this requirement by providing 12-bit resolution
at speeds below 1,000 revolutions per minute.
Of course, the device operates at higher
speeds as well, with reduced resolution,”
states Ralf Kodritsch, Marketing Manager
of austriamicrosystems.
The user can continuously access a serial
digital output and pulse width modulated
(PWM) output at the same time. The angular
position information is provided in the
form of a serial data stream and as a PWM
signal with a resolution of 4096 positions
per revolution (0.09° per step). The
mode selector pin enables the user to adapt
the device to meet the requirements of either
high-precision or higher-speed applications.
The AS5045 offers user-programmable zero-position
setting and diagnostic features, as well
as the option to cascade several devices
in a daisy chain configuration. The device
is immune to magnet misalignment, air gap
and ambient temperature variations. The
AS5045 operates at either 3.3V or 5V. The
operating temperature ranges from -40°C
to +125°C. The AS5045 is available in
a lead-free SSOP16 (5.3mm x 6.2mm) package.
The AS5045 will be available for sampling
in August.
