Highly Integrated Battery Pressure Monitor Sensor
NBP8FD4ST1 and NBP9FD4ST1 are the recommend devices for new designs as the NBP8FD4T1 and NBP9FD4T1 are discontinued.
The NBP8 and NBP9 is a fully integrated battery pressure monitor sensor family in the NXP pressure sensor portfolio that provides a small footprint in a 4 x 4 mm package, low power consumption, PWM, SPI, ready/interrupt and power supply enable.
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 8-bit 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.
