Global technology company TDK Corporation announced the worldwide availability of its InvenSense PositionSense.

The company said that PositionSense is a two-chip, nine-axis sensor offering that enables next-gen positioning accuracy and navigation for applications in wearables, robotics, drones, mobile devices and more.

Smart perception sensors

TDK said that PositionSense ‘Smart Perception’ technology integrates TDK’s lowest-power 6-axis IMU and TMR-based 3-axis magnetometer with on-chip sensor fusion and calibration software to enable fast, accurate orientation tracking and position detection.

“When your device uses PositionSense, users are always on track and never lost - even in a city, field, factory, or location without a satellite connection,” said Joseph Bousaba, CEO of InvenSense, a TDK group company. “Whether for people using their smart glasses, watches, or phone for directions, or for a humanoid navigating a warehouse floor, our PositionSense sensor solution ensures highly accurate and reliable navigation for physical AI devices.”

The company said that the speed and precision of PositionSense’s absolute orientation detection come from the custom integration of its components:

TDK 6-axis SmartMotion IMU, the lowest-power IMU with high-performance MEMS technology and vibration-resistant gyroscope
TDK 3-axis magnetometer, based on tunnel magnetoresistance (TMR) sensor technology, the lowest-power magnetometer with high sensitivity and accuracy, along with magnetic field shock resistance
TDK on-chip sensor fusion software, enabling fast and accurate 9-axis sensor calibration

TDK said that PositionSense is available in four hardware configurations, all with on-chip sensor fusion, gyro-assisted calibration and an easy-to-integrate design for always-on sensing:

ICM-45608 + ICT-15318 - With I2C/SPI/I3C support at 1.8V VDDIO, this PositionSense offering is ideal for IoT applications with a 16g/2000dps Accel/Gyro full-scale range.
ICM-45608 + ICT-15312 - With I2C/SPI support at 1.2V VDDIO, this PositionSense offering is ideal for battery-powered and power-sensitive applications with 16g/2000dps Accel/Gyro full-scale range.
ICM-45689 + ICT-15318 - With the IMU’s extended ±4000 dps gyroscope and ±32 g accelerometer full-scale range, this PositionSense offering improves measurement headroom for high-dynamic motion, while offering I2C/SPI/I3C support with 1.8V VDDIO.
