Housed in a 14-pin VFLGA (14-VFLGA), this is a surface-mount package.
Rated for -40°C to 85°C operating temperature, this sensor is suited for outdoor telecom cabinets, HVAC duct monitoring, and factory-floor enclosures where the ambient stays below 85°C.
No end-of-life notice, no last-time-buy window.
The LIS25BATR measures acceleration over a ±3.85g full-scale range on all three axes (X, Y, Z).
No. The supply voltage range is 1.71 V to 1.99 V. A 3.3 V supply will damage the part. Use a 1.8 V regulator and level-shift the I²C lines if your host runs at 3.3 V.
A common cross-shop candidate is the ST LIS3DH, which also provides X/Y/Z digital output over I²C/SPI but offers selectable ±2g/±4g/±8g/±16g ranges and a wider 1.71 V to 3.6 V supply. The LIS3DH is not pin-compatible (different package) and has a different register map, so a firmware change is required. The LIS25BATR's fixed ±3.85g range and narrower supply are the trade-offs for its specific bandwidth and noise performance.
Not as a drop-in. The LIS25BATR operates at 1.71 V–1.99 V only, while the LIS3DH accepts up to 3.6 V. The package and pinout differ, and the I²C register map is not identical. A board spin and firmware port are required. For a new design, choose based on supply rail and range requirements.
