TLE9012DQU Complex Device Driver

Überblick

Infineon BMS Complex Device Driver provides an advanced ISO26262 compliant software package

Infineon offers a complex device driver (CDD) for battery management systems. The CDD runs on AURIX TC38x microcontroller and supports the usage, the configuration and the supervision of Infineon’s BMS ICs. It acts as a gateway between the battery management system application software and the TLE9012DQU hardware devices and is ISO26262 as well as AUTOSAR compliant.
