NXP Semiconductors NBP9
The NBPx family consists of small QFN (4 mm x 4 mm x 1.98 mm), fully integrated battery pressure monitoring sensors (BPMS). The NBPx BPMS solution integrates an 8bit central processing unit (CPU) and NXP-provided firmware to create the ready-to-use pressure sensor. The battery pressure monitoring sensors have a built in MCU and are capable of sensing the pressure change, making a configuration-based decision, and acting on this decision while providing this information to the host system.| Part No. | NBP9 |
