Infineon Technologies AG has introduced a new family of battery management ICs that enables an optimized solution for battery cell monitoring and balancing. Combining excellent measurement performance with the highest application robustness, these new battery management ICs are suitable for a wide range of industrial, consumer, and automotive applications such as mild hybrid electric vehicles (MHEV), hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV) and battery-powered electric vehicles (BEV). The new TLE9012DQU and TLE9015DQU ICs can be used in safety-relevant applications and are optimized to work together with the AURIX family of microcontrollers.
Based on Infineon's state-of-the-art technologies, the TLE9012DQU IC is capable of performing highly accurate voltage measurements for the state of charge (SoC) and state of health (SoH) calculation. The design of this IC is based on a parallel ADC architecture that enables high accuracy through 16-bit DS ADC technology, excellent noise rejection through high internal oversampling, and advanced sync-on-sample at less than 10 µs across an entire battery pack.
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 cost efficiency of the system. By integrating an error management unit including several inputs and outputs programmable on each TLE9012DQU, the module also enables bidirectional information flow.
