July 7, 2016 – Mouser Electronics, Inc. is now stocking the AS5170 magnetic angular position sensors
from ams. The AS5170 devices are ams’ first magnetic position sensors fully developed using the
automotive industry’s program for ISO 26262 safety compliance to meet the ever-increasing demand
for automotive safety features built into critical vehicle systems.
The ams AS5170 sensors, available from Mouser Electronics, are ams’ first magnetic position
sensors to provide full data path diagnostics, enabling automotive system OEMs to achieve a higher
level of ISO 26262 system-level compliance. The diagnostic system built into the AS5170 devices tests
the entire device, from the Hall sensor front end, through the DSP engine, to the back-end interfaces
and pins.
The AS5170 sensors are qualified to AEC-Q100 Grade 0, and accurately measure the absolute
angle of rotation. Their high, 12-bit output resolution enables precise measurements, even for reduced
angular excursions down to a minimum arc of 90 degrees, making the devices ideal for a range of
safety-critical automotive applications including chassis height, gear shifters, electronic power steering,
exhaust gas recirculation, and brake pedal as well as throttle position sensing.
The AS5170 sensors can benefit from stray magnetic field immunity, enabling unimpaired
operation even in the presence of strong magnetic fields generated by electric motors, high current-
carrying cables and other external devices. This results in highly reliable performance and reduces
system cost eliminating the need for the shielding.
The AS5170 sensors are available in an 8-pin SOIC package with either analog ratiometric
(AS5170A) or digital PWM or SENT (AS5170B) output interfaces.
