The Infineon is a battery monitoring transceiver IC designed for connecting several 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.

Compatibility for ring mode topology
2 Mbit/s data rate for fast communication
Fully transparent communication scheme from UART to iso UART
Integrated internal logic for minimizing pin count on the UART side
High robustness against external noise
Latching error output pin for triggering external microcontroller
