Infineon Technologies AG Battery Management ICs TLE9015DQU

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. Summary of Features Compatibility for ring mode topology Two UART ports for serial communication to host microcontroller Two iso UART interfaces for communication to other BMS ICs 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 Differential current edge triggered iso UART communication interface High robustness against external noise Two external fault inputs (EMM and ERRQ_ext) Latching error output pin for triggering external microcontroller Internal supply monitoring Green Product (RoHS compliant) Benefits Robust communication without need of transformers or common mode chokes Primary-on-Top or Primary-on-bottom selectable without tedious configuration Bi-directional communication scheme using error management logic Ring mode topology for further system availability at low cost Potential Applications Hybrid Electric Vehicle (HEV) Plug-in Hybrid Electric Vehicle (PHEV) Battery Electric Vehicle (BEV) Energy Storage System (ESS) Home Energy Storage system CAV
