可配置，高g ，公司的iMEMS加速度计 Configurable, High g, iMEMS Accelerometer

GENERAL DESCRIPTION

The iMEMS® accelerometer is a configurable, single axis, integrated satellite sensor that enables low cost solutions for front and side impact airbag applications. Acceleration data is sent to the control module via a digital 2-wire current loop interface bus. The communication protocol is programmable for compatibility with various automotive interface bus standards.
