Battery management systems are essential for monitoring and managing the health of batteries used in electric vehicles, industrial energy storage systems, and consumer devices.



Infineon’s Battery Management IC Solutions

Battery monitoring systems for lithium-ion cells need to monitor the voltage and temperature of battery cells, performing critical functions such as cell balancing.

Accurate cell voltage measurement will also ensure that the battery works within safe operating conditions in order to comply with functional safety requirements.

Infineon offers a lineup of battery management ICs that can be used in safety relevant applications where automotive BMS solutions must be ISO26262 compliant and meet safety requirements up to ASIL-D, and are qualified according to AEC Q100

The TLE9012DQU is a multi-channel battery monitoring and balancing system IC designed for Lithium-Ion battery packs. It fulfills four main functions: cell voltage measurement, temperature measurement, cell balancing, and isolated communication to the main battery controller.

The TLE9015DQU UART to Iso-UART transceiver uses its two iso-UART interface pairs to support ring communication.  

It is specifically designed for connecting several dozen TLE9012DQU devices in a daisy chain inside a Lithium-Ion battery and enables bidirectional information flow.

Infineon’s Battery Management ICs are designed and engineered for battery voltages of 400V, 800V and above for the most robust battery management system solution.
