Infineon Technologies TLE9015QU battery management

The TLE9015QU is a general-purpose transceiver IC to be used in multi-cell battery systems to enable the communication between the main host microcontroller and the slaves in the battery. The TLE9015QU enables communication by 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 ensuring a cost-optimized robust system solution. 

Key features

• Two UART ports for serial communication to host microcontroller
• Two iso UART ports for daisy chain communication inside battery pack
• Fully transparent communication scheme from µC to sensing IC
• Ring mode topology compatible (only 1 device needed)

Additional features

• CRC check for communication integrity (no CRC modification)
• High robustness against external noise
• General purpose error pin
• Two external fault inputs with internal latching
• Error output pin to trigger external microcontroller
• Internal supply monitoring
• Low energy sleep mode

Applications

• Hybrid Electric Vehicle (HEV)´
• Plug-in Hybrid Electric Vehicle (PHEV)
• Battery Electric Vehicle (BEV)
• Energy Storage System (ESS)
• Home Energy Storage System (HESS)
• Commercial, Construction and Agricultural Vehicles (CAV)
• Other small vehicles (e.g. eScooter, eBike, etc.)
