FXLS8961AF 3-Axis MEMS Accelerometer

NXP offers their accelerometer for use in a wide range of automotive security and convenience applications

Image of NXP's FXLS8961AF 3-Axis MEMS AccelerometerNXP offers their FXLS8961AF compact 3-axis MEMS accelerometer that is designed for use in a wide range of automotive security and convenience applications requiring excellent offset and sensitivity stability over temperature. The part supports both high-performance and low-power operating modes, allowing maximum flexibility to meet the resolution and power needs of various unique use cases.

A number of advanced, integrated digital features enable designers to reduce the overall system power consumption and simplify host data collection.

The FRDM-STBA-A8961 sensor shield board is an Arduino-compatible sensor expansion shield board for the FXLS8961AF 3-axis accelerometer for precision inclinometer automotive applications.

This evaluation board can be kitted with FRDM-MCXN947 and FRDM-K22F as an alternate MCU option. Evaluation GUI is supported with LPC55S16, K22F, and MCXN platforms.

Features
  • Automotive AECQ-100 qualified
  • 3-axis, ±2 g to ±16 g low-G accelerometer
  • Less than 1 µA in low-power wake-up mode
  • Low noise: 230 µg/√Hz in high-performance mode
  • Integrated digital features reduce system power consumption and simplify host data collection
  • Maximum operating temperature: +105°C
  • Market-leading TCO/TCS: target ±0.2 mg/°C / ±0.005%/°C
  • Two to four times better offset stability over temperature operating range vs previous generation (TCO/TCS)
  • Measurement offset and performance over temperature guaranteed post-board assembly reflow
  • 3x3 QFN package, 0.65 mm pitch with wettable flanks
Applications
  • High-accuracy inclinometers: vehicle tilt, bike lean angle detection, and theft detection
  • Headlights auto-leveling: headlight level adjustment to avoid glare blinding when trunk load changed
  • Car alarms and telematics boxes: OEM or aftermarket
  • eCall: rollover or shock detection when the vehicle is off
  • Smart doors and latches: inclination detection for doors, trunks, and other enclosures
  • Electrical vehicles: shock during recharging, need safe disconnect of power plug
  • Surround-view cameras: capture the surrounding scene when the vehicle is bumped while parked
