NTM88K145ST1

Pressure Sensors Transducers Overview

The NTM88K145ST1 is a highly integrated tire pressure sensor from the NTM88 family, manufactured by STMicroelectronics. It operates within a supply voltage range of 1.2 V to 3.6 V and features an RF/Wireless output type. The component is housed in a 24-pin HQFN-24 package suitable for SMD/SMT installation. It functions reliably across a temperature spectrum from -40°C to +125°C with a typical operating current of 75 uA. This device is designed for board mounting applications requiring robust environmental performance.

Pressure Sensors Transducers Procurement Notes

Verify the manufacturer designation carefully, as this part number is associated with both NXP Semiconductors and STMicroelectronics due to corporate acquisition history. Confirm the specific datasheet version and revision level required for your design integration. Ensure compliance with RoHS and REACH standards as indicated in the product documentation. Check for any recent Product Change Notifications that may affect material declarations or manufacturing locations before finalizing procurement orders.

Pressure Sensors Transducers Selection Notes

Select this component for designs requiring high integration of sensing and communication functions. The NTM88 family offers flexibility for software development and accelerated time-to-market compared to legacy parts. Consider the available pressure ranges and accelerometer tolerances when matching system requirements. Verify compatibility with existing LF and RF infrastructure in the target vehicle platform.

Pressure Sensors Transducers Part Context

The NTM88 series serves as the recommended replacement for the discontinued FXTH8715 high-pressure TPMS family. While the FXTH8715 supported 100-1500 kPa ranges, the NTM88 provides enhanced power efficiency and dual-axis accelerometer architecture. This transition allows for smaller module designs suitable for space-constrained automotive applications while maintaining high precision and reliability standards.

Pressure Sensors Transducers Replacement Considerations

Public confirmed substitute part numbers include NTM88K125ST1, NTM88K135ST1, and NTM88K155ST1 within the same family. These variants share identical packaging and core functionality but differ in specified pressure ranges. Verify the exact differential pressure requirements of your application before selecting an alternative model from the NTM88 lineup.
