SM5106 SILICON MICROSTRUCTURES INCORPORATED • Low Cost OEM Pressure Die Small, Low Cost OEM Pressure Die DESCRIPTION The SM5106 is a very small (1.56mm x 1.56mm) silicon micromachined piezoresistive pressure sensing chip that has been optimized to provide the highest possible accuracy for a die of this size. This performance is achieved through careful resistor placement and mechanical configuration. The small die results In a significant cost saving when compared to larger sensor die. This sensor is intended for high volume applications where cost is a critical factor, such as consumer tire pressure gauges or disposable pressure monitors. The SM5106 is available as an absolute pressure sensor in full-scale ranges of 15 PSI, 30 PSI, 60 PSI, and 150 PSI. It is designed to be mounted on ceramic or PC board substrates by OEM manufacturers. Die are probed, inked, diced, and visually inspected and shipped on tape in rings. Custom pressure ranges available in highvolume applications.
