IAM‑20680HP High‑Performance Automotive‑Grade 6‑Axis Motion‑Tracking Sensor

1. Official Name

IAM‑20680HP (Brand: TDK / InvenSense)

Full Name: High‑Performance Automotive 6‑Axis Motion‑Tracking Device

Chinese: 高性能车规级 6 轴运动跟踪传感器 (IMU‑Inertial Measurement Unit)

2. Core Functions

This device integrates a 3‑axis gyroscope and a 3‑axis accelerometer within a 3×3×0.75 mm LGA‑16 package. It precisely detects motion, attitude, angle and acceleration of objects.

Angular velocity measurement (Gyroscope): rotation direction, tilt angle and rotation speed

Linear acceleration measurement (Accelerometer): vibration, shock, collision and attitude variation

Outputs high‑precision 16‑bit digital signals, communicating directly with MCU via I²C / SPI interface.

3. Key Parameters

Axes: 6‑axis (3‑axis gyroscope + 3‑axis accelerometer)

Measurement Ranges:

‑ Gyroscope: ±250 / 500 / 1000 / 2000 dps (programmable)

‑ Accelerometer: ±2 / 4 / 8 / 16 g (programmable)

Operating Temperature: −40℃ ~ +105℃ (automotive high‑temperature variant)

Supply Voltage: 1.71 ~ 3.6 V, low‑power consumption

Certifications: AEC‑Q100 automotive qualification, PPAP compliant, RoHS compliant

4. Application Scope

1) Automotive Electronics (Primary Application)

‑ Navigation & Vehicle Positioning: Dead‑reckoning positioning compensation for GPS‑denied environments such as tunnels, underground parking garages and high‑rise urban areas

‑ Smart Cockpit: HUD head‑up display, steering wheel attitude detection, automatic rear‑view mirror adjustment

‑ Body Control: Motion detection for power liftgates / power sliding doors, window anti‑pinch, seat attitude monitoring

‑ Telematics / TCU: Collision detection (trigger emergency call), driving‑behavior analysis

2) Industry & IoT

‑ Attitude monitoring and vibration analysis for industrial equipment

‑ Motion control for UAVs and robots

‑ Smart gimbals, AR / VR devices

Why choose IAM‑20680HP over standard IAM‑20680

HP stands for High Performance. It supports wider operating temperature range (−40 ~ 105℃ vs 85℃ for standard version), superior thermal stability and lower gyro noise. Optimized for automotive applications with high‑temperature and high‑vibration working conditions.

5. Summary

IAM‑20680HP is an automotive‑grade 6‑axis IMU from TDK / InvenSense. Featuring high temperature resistance and high accuracy, it is dedicated to vehicle positioning, attitude and motion detection, serving as a core sensor for automotive navigation and smart‑cockpit systems.
