Infineon Technologies TLE9015DQU UART transceiver
Battery monitoring transceiver IC
The TLE9015DQU is a battery monitoring transceiver IC designed for connecting several TLE9012DQU devices in a daisy chain inside a Li-Ion bat-tery. 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.
Key features
- Voltage monitoring of up to 12 battery cells connected in series
- Compatibility for ring mode topology
- Two UART ports for serial communication to host microcontroller
- Two iso UART interfaces for communication to other BMS ICs
Additional features
- 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
Applications
- Battery Electric Vehicle (BEV)
- Mild Hybrid Electric Vehicle (MHEV)
- Hybrid Electric Vehicle (HEV)
- Plug-in Hybrid Electric Vehicle (PHEV)
- 12V Li-Ion battery systems
- Energy Storage System (ESS)
- Home Energy Storage system
