TDK Corporation announced the InvenSense SmartAutomotive? IAM-20381HT high-temperature monolithic 3-axis MotionTracking accelerometer for non-safety automotive applications, such as navigation, infotainment systems, telematics, and more. The launch represents a full transition of the InvenSense SmartAutomotive non-safety product line to 105°C. The IAM-20381HT is part of a fully-compatible, multi-axis, multi-grade portfolio of SmartAutomotive products.

With this release, TDK confirms its leadership in driving the inertial sensors market for both safety and non-safety automotive applications. The IAM-20381HT will be available at distributors worldwide by February 1, 2024. The new stand-alone 3-axis MEMS accelerometer is offered in a thin 3 x 3 x 0.75 mm (16-pin LGA) package and is automotive-qualified based on AEC-Q100 Grade 2. The IAM-20381HT also features two programmable independent interrupt lines, wake-on-motion functionality, and a FIFO up to 4096-bytes, which can lower the traffic on the serial bus interface and reduce power consumption by allowing the system processor to burst-read sensor data and then go into a low-power mode.

Such features enable a variety of motion-activated functions such as anti-theft, vehicle security, and driving style data recording. TDK will demonstrate this and other technologies at the Consumer Electronics Show (CES) from January 9-12, 2024, in Las Vegas. Find TDK in the CES Central Hall (LVCC) at booth #20521.
