STMicroelectronics’ AIS2IH three-axis linear accelerometer brings enhanced decision, temperature stability, and mechanical robustness to non-safety automotive purposes.
STMicroelectronics has launched AIS2IH, a three-axis linear accelerometer that brings enhanced decision, temperature stability, and mechanical robustness to non-safety automotive purposes together with anti-theft, telematics, infotainment, tilt/inclination measurement, and automobile navigation. It additionally paves the way in which to new performance-demanding purposes in automotive, medical, and industrial segments.
Leveraging ST’s main positions in each MEMS and automotive applied sciences, the AIS2IH ensures market-leading reliability whereas delivering high-performance movement sensing over a large -40ºC to +115ºC working temperature vary. Furthermore, the accelerometer options ultra-low energy consumption in a compact LGA-12 land grid array package deal, at an ultra-competitive value.
With 5 completely different working modes, together with one high-performance mode (HPM) and 4 low-power modes (LPM), the system helps switching between modes on the fly to optimize decision and energy consumption for the precise utility necessities at any time.
Collectively, the prolonged operating-temperature vary with enhanced efficiency and cost-effectiveness allow the AIS2IH to handle rising automotive purposes corresponding to digital drive recorders, driver monitoring, vertical stage sensing in automobile suspension, and door automation. The sensor can be suited to industrial IoT (IIoT) purposes corresponding to 5G sensible antennas in addition to delicate medical purposes like pacemakers, which require ultra-low energy consumption, compact measurement, and excessive decision at uncompromised reliability.
ST’s new automotive accelerometer has user-selectable full scales of ±2g, ±4g, ±8g, and ±16g, and is able to measuring accelerations with output knowledge charges (ODR) configurable within the vary from 1.6Hz to 1.6kHz, with embedded configurable digital low-pass and high-pass filters. Typical noise density is 90µg/√Hz when working in high-performance mode. The working present at 3V is 110μA in HPM and 0.67μA in LPM at 1.6Hz. The embedded 32-level FIFO and the motion- and activity-detection capabilities contribute to conserving the system-level energy consumption inside a decent funds.
