TDK announces new 3-axis accelerometer, finalising transition of SmartAutomotive non-safety product family to 105°C

TDK have 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.

“With this launch, TDK completes the transition from temperature grade 3 to grade 2 of the entire SmartAutomotive non-safety product line,” said Alberto Marinoni, Senior Director Product Marketing Automotive at InvenSense, a TDK Group company. “Now TDK provides a complete lineup of pin-to-pin and register-compatible inertial sensors for automotive while ensuring scalability of customer applications up to 105°C.”

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.
