TLE9015QU

The TLE9015QU belongs to Infineon´s Battery Management Transceiver IC product family

The TLE9015QU is a battery monitoring transceiver IC designed for connecting several TLE9012AQU 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 TLE9012AQU.

Summary of Features

• Two UART ports for serial communication to host microcontroller
• Two iso UART ports for daisy chain communication inside battery pack
