ams Announces Automotive-Grade Sensor IC for Shifter Position Detection in Hybrid, Battery-Powered and Conventional Vehicles

ams (SIX: AMS), a leading worldwide supplier of high performance sensor
solutions, today released the AS5200L, a dual-die magnetic rotary
position sensor with an I2C interface that enables the
development of new space-saving designs in safety-critical automotive
applications.

The AEC-Q100 grade 1 qualified AS5200L joins ams’ extensive portfolio of
magnetic position sensors, with its unique feature set focused at
electrified powertrain drive-by-wire control functions, such as
shift-by-wire for both traditional stick and rotary shifters, and pedal
applications.

ams’ traditional high-performance and reliable position sensing
technologies are reinforced in the AS5200L by the provision of dual
dies. The stacked configuration of the dies means they may be paired
with a single small target magnet while providing identical measurement
outputs from each die. Separate package pins are provided for each die
to prevent an electrical fault in the device from affecting both dies.

Like all ams magnetic position sensors, the AS5200L benefits from
inherent immunity to stray magnetic fields and produces highly accurate
and repeatable measurements even in noisy magnetic environments. The
result is very reliable performance and reduced system cost, since there
is no need for the shielding typically required by competitive magnetic
position sensor ICs.

The AS5200L is housed in an MLF-16 package, with a space-saving
footprint of just 5mm x 5mm, and with exposed pads and wettable flanks
for fast and simple board-level solder joint inspection. The AS5200L is
particularly well suited for automotive system designers seeking to
implement robust, accurate rotary position sensing in vehicle
electrification applications with tight space constraints, such as gear
shifters and pedals, and in various other contactless potentiometer
applications such as knobs and joysticks.

The provision of an I2C interface allows for easy programming
of operating parameters by a host microcontroller without the need for a
dedicated programmer. The AS5200L can provide its angle measurements via
the I2C interface or as a PWM signal. Angle measurements are
supplied in 12-bit resolution, and the maximum error attributable to
inherent non-linearity is a maximum ±1°.

The AS5200L offers low power consumption in active and stand-by modes. A
smart low-power mode automatically reduces power consumption, resulting
in average current of just 1.5mA when polling every 100ms.

The sensor measures rotation over a full 0° to 360° rotation by default.
A smaller range can be set by programming a start and stop position into
the chip’s one-time programmable (OTP) memory.

“The AS5200L is perfect for embedded safety-critical automotive
applications in which high accuracy, redundancy and a very small
footprint are of high priority,” said Thomas Mueller, Director of
Marketing for position sensors at ams. “The dual-die AS5200L with its
redundant high-resolution 12-bit I²C or PWM outputs, is ideally suited
for shift-by-wire applications in hybrid, battery-powered and
conventional vehicles. With its high performance and redundancy, the
AS5200L can help automotive OEMs achieve up to ASIL D compliance at the
system level.”

The AS5200L is available in production volumes. Unit pricing is $1.45 in
high volumes.

An evaluation board for the AS5200L is available from the ams ICdirect
online store. For sample requests or for more technical information, go
