The German semiconductor manufacturer Infineon Technologies launched a new family of battery management ICs, including TLE9012DQU and TLE9015DQU. 

Suitable for industrial, consumer and automotive, including mild hybrid electric vehicles (MHEV), hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV) and battery-powered electric vehicles (BEV), these ICs enable an optimised solution for battery cell monitoring and balancing.

According to a press release from the company, the additional applications include energy storage systems and battery management systems for electric two/three-wheelers.

Combining measurement performance with application robustness, the new battery management ICs are a competitive system-level solution for battery modules, cell-to-pack and cell-to-car battery topologies, the release added.

The new battery management ICs can be used in safety-relevant applications; the automotive BMS solutions meet safety requirements up to ASIL-D and are ISO26262 compliant, the company said.

These products are optimised to work together with the AURIX family of microcontrollers and functional safety capable power management ICs thanks to the Complex Device Driver. 


Based on a parallel ADC architecture, the multichannel battery monitoring and balancing system IC can perform highly accurate voltage measurements for the state of charge (SoC) and state of health (SoH) calculation – the key requirements for any battery management system, the release stated.

In addition, the device is ASIL-D compliant monitoring and balancing IC designed for lithium-ion battery packs. A microcontroller can control it directly via UART or via an isolated UART interface with the new TLE9015DQU iso-UART transceiver IC.


While the TLE9015DQU is a battery monitoring transceiver IC designed for connecting several TLE9012DQU devices in a daisy chain inside a Li-Ion battery. This device uses its two UART and Iso-UART interface pairs to support ring communication, improving the system's cost efficiency.

By integrating an error management unit including several inputs and outputs programmable on each TLE9012DQU, the module also enables bidirectional information flow, the company noted.
