The TLE9015DQU is a battery monitoring transceiver IC designed for connecting several TLE9012DQU devices in a daisy chain inside a Li-Ion battery. By means of its two UART and iso UART interface pairs it can support ring communication improving the availability of the system by a low cost.It also enables bidirectional information flow by including an error management unit including several inputs and outputs that are programmable on each TLE9012DQU.
