New Product Introduction

Infineon TLE9012AQU

The TLE9012AQU is a multi-cell battery monitoring and balancing system IC

Product sample of Infineon's TLE9012AQU system IC

As a multi-cell battery monitoring and balancing system IC the TLE9012AQU is designed for Li-Ion battery packs used in full hybrid electric vehicles (FHEV), plug-in hybrid electric vehicles (PHEV), battery electric vehicles (BEV) as well as in mild hybrid electric vehicles (MHEV) and other batteries such as12 V Lithium-Ion batteries and stationary batteries. The TLE9012AQU is qualified for automotive applications according to AEC-Q100.

The TLE9012AQU provides the main function of monitoring the temperature of the battery and voltage of each cell as well as the communication to the host controller.
