Description The TLE9015QU is a general purpose transceiver IC to be used in battery systems to enable the communication between the main host microcontroller and the cell supervision ICs which are usually connected to the battery module potential. The IC is designed for Li-Ion battery packs used in hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), battery electric vehicles (BEV) as well as stationary Lithium-Ion batteries. Additionally to the physical layer translation, the TLE9015QU offers the possibility to communicate potential errors detected in a cell inside the battery pack to the main microcontroller.
