Our industry-leading ASR0x2 line of tunneling magnetoresistive
(TMR) smart angle sensors are smaller, faster, more accurate,
and lower power than other magnetic angle sensors.
A diametrically-magnetized disk magnet provides a magnetic
field of 6 to 20 mT as illustrated at right.
On-Axis or Off-Axis
With proper magnet placement, ASR0x2 sensors can be used off-axis
with the same accuracy as the standard on-axis configuration
(see this Application
Bulletin for specifics).
sensors are factory calibrated and internally temperature
Three Interface Versions
The family includes versions with three different interfaces,
the SPI ASR002, the I²C ASR012, and the ABZ ASR022.
Key features include:
Ultraminiature 2.5 x 2.5 x 0.8 mm
SPI, I²C, or ABZ interfaces
Flexible 2.2 to 3.6 V supply range
Low 4 mA typical supply current
Robust airgap and misalignment tolerances
Full -40 °C to 125 °C operating
boards provide easy connections to ASR0x2 Angle Sensors. The
boards have a sensor, the recommended bypass capacitor, and
a six-pin header connected to each of the sensor I/O pads.
The boards are just 0.5 by 0.6 inches (12 by 15
The ASR002 and ASR012 demonstration boards include a diametrical
magnet, magnet fixturing, and an interface board with a microcontroller.
Easy-to-install Windows software provides a graphical user
interface showing the sensor output and allowing sensor parameters
to be programmed.
The ASR022 Demonstration Board includes a four-digit display, LEDs for A, B, Z,
and Direction outputs, and two AAA batteries for power.

NVE presented recently at a Webinar hosted by Angst and Pfister on the
BeFAST e-mobility charging platform, which includes IL7xx
isolators. With their best-in-class isolation and CMTI, V-Series isolators
are the perfect complement for silicon carbide MOSFETs.
