The ADXL185B z-axis sensor and the ADXL189B x-axis sensor are g range configurable, integrated single-axis satellite sensors, compliant with the PSI5 Version 1.3 specification. The ADXL185B / ADXL189B enable low cost solutions for front and side impact airbag satellite sensor applications. Acceleration data is sent to the control module via a digital 2-wire current loop interface bus.
The sensor g range is configurable to provide full-scale ranges from ±30 g to ±480 g. The devices can also be configured to transmit data from multiple g ranges during predefined time slots, in accordance with the PSI5 specification. The devices transmit 10-bit acceleration data to the control module and can be configured to include either a 1-bit parity check or a 3-bit cyclic redundancy check (CRC). Each device has a unique electronic serial number.
The ADXL185B / ADXL189B are available in a 16-lead, narrow-body SOIC package with an exposed pad. The ADXL185B / ADXL189B are specified to operate over the full automotive temperature range of −40°C to +125°C.
APPLICATIONS
- Front impact crash sensing
- Side impact crash sensing
