New three-axis accelerometer for non-safety automotive applications

TDK Corporation has launched the InvenSense SmartAutomotive IAM-20381HT high-temperature monolithic three-axis MotionTracking accelerometer for non-safety automotive applications, including navigation, infotainment systems, telematics, and more. The launch represents a full transition of the InvenSense SmartAutomotive non-safety product line to 105C.

The IAM-20381HT is part of a fully-compatible, multi-axis, multi-grade portfolio of SmartAutomotive products. The company confirms its leadership in driving the inertial sensors market for safety and non-safety automotive applications with this release.

“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 of 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 105C.”

The new stand-alone three-axis MEMS accelerometer is supplied in a thin 3mm x 3mm x 0.75mm (16-pin LGA) package and is automotive-qualified based on AEC-Q100 Grade 2. The device 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 decrease power consumption by enabling the system processor to burst-read sensor data and then go into a low-power mode. Such features allow a variety of motion-activated functions such as anti-theft, vehicle security, and driving style data recording..
