1 General description

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 4 mm x 4 mm x 1.98 mm wettable-flank QFN, and is qualified to AEC-Q100

grade 1 and MSL 3 classifications.
