NXP Semiconductors BMI7018 18-Channel Li-Ion Battery Cell Controller ICs are lithium-ion battery-cell controller ICs for use in industrial applications, such as energy storage systems (ESS) and uninterruptible power supply (UPS) systems. The BMI7018 ICs offer a Transport Protocol Link (TPL3 - proprietary isolated daisy chain protocol of NXP) and Serial Peripheral Interface (SPI) for communication with the host microcontroller unit (MCU). These devices support high-precision cell voltage and temperature measurements along with various cell voltage balancing strategies. Aside from an SPI interface to enable direct communication with the host MCU, the ICs provide alternatively a daisy chain communication interface that supports capacitive and inductive isolation between nodes.
