UNTERPREMSTAETTEN, Austria -- ams AG on Tuesday (Nov. 13)
introduced a new family of magnetic rotary position sensors with
advanced safety features for automotive applications requiring
Highly integrated systems-on-chip, all magnetic rotary position
sensors from ams incorporate Hall magnetic sensing elements, an
analog front end and digital signal processing to produce
accurate and precise angle measurements. The new 60 Series
sensors Ė the AS5161 and AS5261 (with a digital PWM output) and
the AS5162 and AS5262 (with analog voltage output) Ė now also
feature automotive protection features that enable
vehicle manufacturers to achieve ISO26262 compliance in
The rigorous ISO26262 standard for automotive functional safety
requires vehicle manufacturers to achieve high levels of
reliability, to analyze the effects of the failure modes of
components and systems, and to take measures to guarantee
functional safety in the event of a predictable failure.
The 60 Series sensors enable manufacturers to achieve ISO26262
compliance by offering very high reliability, comprehensive
analysis of the effects of direct and indirect dangerous faults,
and very low Failure In Time (FIT) rates. Dual stacked dice
(single package) versions, which are fully redundant, the AS5261
and AS5262 sensors can be used in applications requiring the
highest ASIL D safety grading.
ams has also enabled enhanced self-diagnostic capabilities in
this new generation of automotive position sensors. For example,
they can detect a failed input voltage, and the broken ground
detection feature with pull-down resistor operates even at high
temperatures, unlike in competitive products.
With this new generation of sensors, ams has also implemented a
number of power-saving features, resulting in leading-edge
efficiency. While the 60 Series devices typically draw a 10mA
supply current, many competitive devices draw more than 15mA.
