High-Performance Automotive 6-Axis MotionTracking® Device

OVERVIEW

The IAM-20680HP is a Grade 2 (-40ºC to 105ºC) 6-axis MotionTracking device for Automotive non-safety applications that combines a 3-axis gyroscope and a 3-axis accelerometer in a small 3 × 3 × 0.75 mm³ (16-pin LGA) package. It also features a 4096-byte FIFO that 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. IAM-20680HP, with its 6-axis integration, enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices, guaranteeing optimal motion performance.

The gyroscope has a programmable full-scale range of ±250 dps, ±500 dps, ±1000 dps and ±2000 dps. The accelerometer has a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g. Factory-calibrated initial parameters of both sensors reduces production-line calibration requirements.

Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts. The device features I²C and SPI serial interfaces, a VDD operating range of 1.71V to 3.6V, and a separate digital IO supply, VDDIO from 1.71V to 3.6V.

IAM-20680HP Applications

Dead Reckoning

Vehicle To Vehicle Location

Vision Systems

Augmented Reality HUD

High performance 6-axis IMUs enhance positioning systems when GPS/GNSS signal is not available or reliable. Gyroscope and accelerometer outputs are fused to determine vehicle position even in multi-level parking or tunnels.

The accelerometer and gyroscope data fusion provides incredibly accurate location data for Vehicle to Vehicle systems and infrastructure.

6-axis IMUs enable camera image stabilization to compensate for road vibrations, allowing crisp and stable rear view image in electronic mirrors.

High performance 6-axis IMUs enable overlay projection stabilization, significantly increasing driver's awareness of surroundings.

Telematics

Lift Gate Control

In-Vehicle Infotainment

Smart Antenna

The accelerometer enables crash detection which can trigger emergency calls, and the gyroscope allows for vehicle positioning and driving style analysis.

Door control systems use accelerometer and gyroscope sensors to monitor doors dynamic conditions during automatic movement.

6-axis IMU sensors enable advanced features and deliver a superior user navigation experience.

6-axis IMUs in combination with GNSS enables local positioning computing, simplifying smart antenna installation as it requires only a power connection.
