NXP NBP8FD4T1

The NBP9 family is a fully integrated battery pressure monitoring sensor (BPMS). The NBP9 BPMS solution integrates an 8-bit central processing unit (CPU) running on factory-embedded firmware with serial data and PWM output interfaces to create the ready-to-use battery pressure monitor sensor. The NBP9 includes unique autonomous features such as periodic data management with host notification, pressure change detection with host wake up, and self-test. The NBP9 is packaged in a small 4mm × 4mm × 1.98mm wettable-flank QFN, and is qualified to AEC-Q100 grade 1 and MSL 3 classifications.
