STMicroelectronics L99BM114-TR, Li Ion Charger IC Lithium-ion, 9.6 V to 64V Input 5V Output 200 mA, TQFP 64-Pin

The STMicroelectronics Li-ion battery monitoring and protecting chip for high-reliability industrial applications and energy storage systems. Up to 14 stacked battery cells can be monitored to meet the requirements of 48 V 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 7 NTCs. The information is transmitted through SPI communication or isolated interface.

• Supports busbar connection without altering cell results
• Embedded NVM for customer parameters storage
• System safety ready
