Topics
- 2023-10-31 HP type (high performance) has been added to the EWTS5G series.
- 2019-12-24 6DoF Inertial Sensor for Automotive (6in1 Sensor) has been commercialized.
Features
Feature #1 Function Safety compliance (ISO26262) for automotive safety system
- Compatible with ASIL-D functional safety development
This sensor complies with ISO26262 according to the user system safety level (ASIL: Automotive Safety Integrity Level) , supports the construction of argument by providing necessary documents, and guarantees the quality for automotive applications.
Feature #2 6DoF sensors on one single MEMS structure with high accurate and for more system design flexibility
- Orthogonality : ≦0.01° between Gyro and Acc axis
The misalignment between Acc and Gyro axis deteriorates data accuracy because Acc and Gyro sensors are comprised of the multiple chips in the conventional inertial sensor. 6in1 inertial sensor adapts one single chip solution in which all 6 axis of Acc and Gyro sit together. And all 6 axis are orthogonal and enables high accuracy data in spite of the installation posture.
Conventional sensor chip configuration
≦1.7°
6in1 sensor chip configuration
Orthogonality
≦0.01°
Feature #3 Contribute for compact and simple ECU system design
- 6DoF one package ：4.5 x 4.5 x 1.1 mm
This sensor adapts electrostatic MEMS and encapsulates MEMS and ASIC by wafer level packaging to realize the world compact and low profile 6DoF inertial sensor. This enable automotive ECU system simple and smaller.
Feature #4 Dimple processing contributes to improved mounting quality
Dimple processing enables soldering fillet visible at the side of lead terminals. This can confirm each terminal soldering correctly to the substrate land by the fillet visible inspection.
