YPRES, Belgium, June 21, 2010 /PRNewswire/ -- Melexis today
releases the MLX92211, second generation of Automotive Hall-Effect
Latch sensors. The MLX92211 comes as a great successor of the
worldwide famous USx88x series by Melexis. This brand new platform
has been meticulously designed to deliver a standard product with
tremendous performance and exceptional robustness for more and more
stringent automotive requirements such as Electrical Power Steering
(EPS), Window lifters/Sunroof, Seat Adjusters, Wipers or Motor
Commutation.
The MLX92211 features a very sensitive Hall-Effect sensor
operating from 2.7 to 24 volts, covering automotive, consumer and
industrial applications. With Latching magnetic behavior, the open
drain output is switched ON and OFF by applying South and North
magnetic field perpendicularly to the package top side, typically
the case with rotary applications using "on-shaft" multi-poles ring
magnet.
Especially designed for automotive applications, the device
integrates all protections required when using "integrated" or
"remote" sensors like very high electro-static discharge (ESD)
rating, reverse supply voltage protection, output short circuit
protection and even more.
Brand New Platform
The MLX92211 core is based on a high voltage sub-micron process
ideally suited to handle low and high operating voltage from 2.7 to
24 volts as well as low and high operating temperature from -40 to
150 degree Celsius.
The whole magnetic core was reinvented in this platform with a
special focus on the offset cancellation system to allow faster and
more accurate processing while being temperature insensitive. A
negative temperature coefficient of -1000ppm/degC was implemented
to compensate the natural behavior of magnets becoming weaker with
rise in temperature.
The result leads to very stable and accurate magnetic switching
points of typically +/-3mT (milliteslas)at 25degC, while the output
is updated every 6us (micro-seconds) with a jitter of only +/-3us,
thus increasing repeatability factor within the application.
Packaging & Availability
The MLX92211 is packaged in the 3-pin Thin SOT (TSOT) package
for SMD mounting. This package has been specially selected to be
"face-up" meaning the silicon die is facing the package top side.
Respectful of the environment, the SE package is fully "Green"
compliant including notably RoHS (Restriction of Hazardous
Substances), Lead-Free (Pb-Free) and Halogen-Free compliance.
The MLX92211 is available for high volume production with
engineering samples available on request.
