FXPS71407BPST1
Overview
The FXPS71407BPST1 is a high-performance absolute pressure sensor designed for safety-critical automotive applications. It utilizes a PSI5 digital interface and includes redundant pressure transducers to meet ISO 26262 functional safety requirements. The device integrates a capacitance-to-voltage converter, an anti-aliasing filter, and a 10-bit Sigma-Delta ADC to provide reliable pressure measurements between 50.9 kPa and 126.5 kPa.
Why Choose This Part
This sensor offers exceptional reliability through its redundant transducer architecture and development following ISO 26262:2011 standards. It supports a wide supply voltage range of 4.2V to 16V and provides high-speed digital output via the PSI5 protocol, reducing cabling requirements in complex automotive networks. The integrated temperature compensation and 10-bit resolution ensure stable performance across an operating temperature range of -40 deg C to 125 deg C.
Applications
Key Specifications
Getting Started
Implementation requires a microcontroller with a PSI5 transceiver or a dedicated PSI5 interface IC to handle the current-modulated digital protocol. Engineers should refer to the NXP FXPS7xxx series application notes for PCB mounting guidelines of the 16-pin HQFN package to ensure proper stress isolation of the pressure sensing element. Evaluation is typically performed using NXP sensor toolbox kits or custom PSI5 interface hardware.
