Infineon’s new Battery Administration ICs offer superb measurement functionality and permit optimized battery life time

MUNICH, April 26, 2022 /PRNewswire/ — Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) introduces a new loved ones of battery management ICs, which include TLE9012DQU and TLE9015DQU. The ICs permit an optimized answer for battery mobile checking and balancing. Combining exceptional measurement performance with the best application robustness, the new battery management ICs are a aggressive procedure-degree answer for battery modules, cell-to-pack and cell-to-car or truck battery topologies. The units are suited for a wide assortment of industrial, buyer and automotive applications these types of as gentle hybrid electrical cars (MHEV), hybrid electrical motor vehicles (HEV), plug-in hybrid electrical motor vehicles (PHEV) and battery-driven electrical autos (BEV). Additional programs consist of power storage programs and battery administration devices for electric two- and 3-wheelers.

The new battery administration ICs from Infineon empower an optimized answer for battery cell monitoring and balancing. They merge exceptional measurement functionality with the greatest software robustness.

“With the TLE9012DQU and TLE9015DQU, Infineon achieves an critical milestone and completes its battery administration system presenting”, claims Finn Felsberg, Senior Vice President and Common Manager Automotive Energy Integration and Offer at Infineon. “Buyers profit from the interoperability of Infineon’s components as effectively as from the wide software featuring. As a end result, development attempts can be minimized and time to market can be diminished.”

The new battery administration ICs can be made use of in security relevant apps: the automotive BMS options meet up with protection specifications up to ASIL-D and are ISO26262 compliant. Moreover, these merchandise are optimized to work collectively with the AURIX™ relatives of microcontrollers and practical safety able energy management ICs many thanks to the Advanced Gadget Driver. This gives a full answer for voltage and temperature sensing, as perfectly as balancing and conversation throughout a wide range of battery options.

Dependent on Infineon’s state-of-the-art technologies, the multichannel battery monitoring and balancing method IC TLE9012DQU is able of accomplishing extremely exact voltage measurements for condition of demand (SoC) and condition of wellbeing (SoH) calculation – the crucial specifications for any battery management technique. In addition, the system is an ASIL-D compliant monitoring and balancing IC intended for lithium-ion battery packs. It can be controlled directly by a microcontroller by way of UART or by way of an isolated UART interface with the new TLE9015DQU iso-UART transceiver IC.

The style and design of the TLE9012DQU is based on a parallel ADC architecture. This allows significant precision as a result of 16-little bit DS ADC technologies, excellent sound rejection as a result of superior internal oversampling, and highly developed sync-on-sample at a lot less than 10 µs throughout an full battery pack. In addition, dependence on external parts for conclude-of-existence precision can be lessened, if not eradicated.

The TLE9015DQU is a battery checking transceiver IC made for connecting several TLE9012DQU gadgets in a daisy chain inside a Li-Ion battery. This device takes advantage of its two UART and Iso-UART interface pairs to assistance ring communication, bettering the cost effectiveness of the technique. By integrating an mistake administration unit together with numerous inputs and outputs programmable on every single TLE9012DQU, the module also allows bidirectional data circulation.


TLE9012DQU and TLE9015DQU are the two introduced and obtainable for use in output designs. Extra details is obtainable at
