Product Details
The ADXL152 is a g range configurable single-axis integrated satellite sensor, compliant to the PSI5 V2.1 specification. The ADXL152 enables 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 g range of the sensor is configurable to provide full-scale acceleration measurements of ±120 g, ±240 g, or ±480 g. Additionally, the device can be configured to transmit data from multiple g ranges during predefined time slots, in accordance with the PSI5 specification. The device transmits 10- or 16-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). The ADXL152 has a unique electronic serial number.
The ADXL152 is available in a 12-lead, 4 mm × 4 mm LFCSP package. The device is specified to operate over the full automotive temperature range, from −40°C to +125°C.
Applications
- Front impact crash sensing
- Side impact crash sensing
