China, May 13, 2021 – STMicroelectronics AIS2IH three-axis linear accelerometer brings higher measurement to non-safety automotive applications such as car anti-theft, telematics, infotainment, tilt/roll measurement, vehicle navigation and more Resolution, temperature stability and mechanical strength also pave the way for emerging automotive, medical and industrial applications where performance is critical.
Leveraging ST’s leadership in MEMS technology and automotive technology, the AIS2IH offers market-leading reliability, high-performance motion measurement capabilities over a wide operating temperature range of -40ºC to +115ºC. In addition, the new accelerometer adopts ultra-low power technology and compact LGA-12 grid array package, and the price is very competitive in the market.
The new product has five different operating modes: one high-performance mode (HPM) and four low-power modes (LPM), which can be dynamically switched at any time between modes to optimize measurement resolution and power consumption for specific applications need.
The extended operating temperature range combined with higher performance and cost-effectiveness enables the AIS2IH to meet emerging automotive application requirements such as digital dash cams, driver monitoring, suspension height sensing, and automatic door opening and closing. The new sensor is also suitable for Industrial Internet of Things (IIoT) devices such as 5G smart antennas and sensitive medical instruments such as pacemakers. These applications require components that must be ultra-low power, compact in size, and high resolution without sacrificing reliability. sex at the cost.
ST’s new automotive accelerometer allows user-selectable ranges of ±2g, ±4g, ±8g, and ±16g full scale, output data rate (ODR) settable from 1.6Hz-1.6kHz, and built-in configurable digital Low pass/high pass filter. In high-performance mode, the typical noise density is 90µg/√Hz, and the operating current is 110µA at 3V; in the 1.6Hz low-power mode, the operating current is 0.67µA at 3V. The product has built-in 32-level FIFO and motion/activity detection to help tightly control system-level power consumption.
AIS2IH has passed the AEC-Q100 automotive standard certification and is now providing engineering samples. The chip package is a 2mm x 2mm LGA package with a Wettable Flank structure.
