The TLE9015QU is a general-purpose transceiver IC to be used in multi-cell battery systems to enable the communication between the main host microcontroller and the slaves in the battery. The TLE9015QU enables communication by connecting several TLE9012AQU devices in a daisy chain inside a Li-Ion battery. By means of its two UART and iso UART interface pairs, it can support ring communication ensuring a cost-optimized robust system solution. 

 

Key features

  • Two UART ports for serial communication to host microcontroller
  • Two iso UART ports for daisy chain communication inside battery pack
  • Fully transparent communication scheme from µC to sensing IC
  • Ring mode topology compatible (only 1 device needed)

 

Additional features

  • CRC check for communication integrity (no CRC modification)
  • High robustness against external noise
  • General purpose error pin
  • Two external fault inputs with internal latching
  • Error output pin to trigger external microcontroller
  • Internal supply monitoring
  • Low energy sleep mode

 

Applications

  • Hybrid Electric Vehicle (HEV)´
  • Plug-in Hybrid Electric Vehicle (PHEV)
  • Battery Electric Vehicle (BEV)
  • Energy Storage System (ESS)
  • Home Energy Storage System (HESS)
  • Commercial, Construction and Agricultural Vehicles (CAV)
  • Other small vehicles (e.g. eScooter, eBike, etc.)
