Functional safety compliance for automotive safety system (ISO26262)

sensors 6-in-1 functional-safety Panasonic Industry

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.

Highly accurate 6DoF MEMS sensors on single die, improving system design flexibility

Sensors 6-in-1 sensor chip-configuration

Orthogonality: ≦0.5° 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.

Compact and simple ECU system design

Sensors 6-in-1 cross-sectional-view

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 enables automotive ECU System to be simple and smaller.

  1. Au Wire
  2. Leadframe

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.
