AIS2DW12 - Robust, Low-Power Automotive Accelerometer for Secure Remote Key Fobs
The STMicroelectronics released the AIS2DW12 which is an ultra-low-power three-axis linear accelerometer which leverages on the robust and mature manufacturing processes already used for the production of micro-machined accelerometers and designed to address non-safety automotive applications. The new automotive accelerometer makes Passive Keyless Entry (PKE) radio fobs tough enough to survive the inevitable drops and scrapes in a lifetime of use.
The AIS2DW12 accelerometers features motion awareness making it a superior theft resistance withstanding for a long time using its ultra-low power consumption feature. This feature makes it ideal for automotive applications where vehicle owner can enjoy greater security without taking extra care of a fragile fob, and with longer battery life as a bonus. Additionally it can be applied to car key applications, Inclination / orientation detection, Motion-activated functions, Gesture recognition, Free-fall detection and Smart power saving applications.
