Frequently Asked Questions
How does the SP370-23-156-0 communicate with a host microcontroller, and what resolution does it provide?
The SP370-23-156-0 uses an I2C interface for two-wire digital communication, outputting 10-bit pressure data to a host controller. This resolution enables accurate pressure differentiation across the sensor's range, supporting reliable tire pressure monitoring in automotive TPMS applications where 1% accuracy is required.
What are the physical dimensions of the SP370-23-156-0 and how does the package benefit PCB integration?
The sensor is housed in a surface-mount plastic package measuring 11.09 mm in length, 6.05 mm in breadth, and 3.9 mm in height. This compact footprint allows it to be placed on small TPMS module PCBs with standard pick-and-place assembly, minimizing system size while maintaining robust environmental sealing.
For automotive TPMS designs, how much current does the SP370-23-156-0 draw during active operation?
The SP370-23-156-0 draws a maximum operating current of 15 mA, making it suitable for battery-powered tire pressure modules where power budgets are constrained. Automotive TPMS systems typically use coin cells or rechargeable batteries, and the sensor's low current consumption helps extend battery life well beyond 5 years in typical duty cycles.
