L9963E-TR, Battery Management Automotive chip for battery management applications daisy chain up to 31 devices
Power\Power Management ICs\Battery ManagementL9963E Multicell Battery Monitoring & Balancing IC
STMicroelectronics L9963E Multicell Battery Monitoring & Balancing IC is a Li-ion battery monitoring and protecting chip for high-reliability automotive applications and energy storage systems. Up to 14 stacked battery cells can be monitored to meet the requirements of 48V and higher voltage systems. Each cell voltage is measured with high accuracy, as well as the current for the on-chip coulomb counting. The device can monitor up to seven NTCs. The information is transmitted through SPI communication or an isolated interface. Multiple L9963E can be connected in a daisy chain and communicate with one host processor via the transformer isolated interfaces, featuring high-speed, low EMI, long-distance, and reliable data transmission.
