Infineon has introduced a new series of battery management ICs designed for battery modules, cell-to-pack topologies and cell-to-car topologies in EVs, hybrids and energy storage systems.
The TLE9012DQU is a multichannel battery monitoring and balancing system that measures battery voltage for state of charge and state of health calculations, and can be controlled directly by a microcontroller through UART. The company says its parallel ADC architecture “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 intended for connecting many TLE9012DQUs inside a battery. It uses two UART and Iso-UART interface pairs for ring communication and has an error management unit comprised of multiple inputs and outputs which supply bidirectional information flow.
Both ICs are ASIL-D and ISO26262-compliant, and are available now.
“Customers benefit from the interoperability of Infineon’s components as well as from the broad software offering. As a result, development efforts can be minimized and time to market can be reduced,” said Senior VP Finn Felsberg.
