NBP8
NBP8 is Battery pressure monitor sensor manufactured by NXP Semiconductors.
description
The NBP8 family is a fully integrated battery pressure monitoring sensor (BPMS). The NBP8 BPMS solution integrates an 8-bit central processing unit (CPU) running on factory-embedded firmware with serial data interface to create the ready-to-use battery pressure monitor sensor.
The NBP8 includes unique autonomous features such as periodic data management with host notification, pressure change detection with host wake up, and self-test.
The NBP8 is packaged in a small 4 mm x 4 mm x 1.98 mm wettable-flank QFN, and is qualified to AEC-Q100 grade 1 and MSL 3 classifications.
