NBP9
Battery pressure monitor sensor
Rev. 2.4 — 11 March 2022 Product data sheet
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.
2 Features and benefits
• Transducer measurement interfaces with low-power AFE:
– 10-bit compensated pressure sense element
– 8-bit compensated internal device temperature measurement
– 8-bit compensated internal device voltage measurement
• 12-entry pressure FIFO
• Selectable host wake-up indications:
– fixed pressure threshold
– relative pressure threshold
– pressure rate of change threshold
• Client SPI to support host access to internal peripherals, registers, and memory
• Generation of PWM signal encoding error status and pressure measurement
• Qualified in compliance with AEC-Q100, Rev. H
• User-selectable sampling interval
• Low-voltage detection
