TLE9015QU

Overview

The TLE9015QU belongs to Infineon´s Battery Management Transceiver IC product family

The TLE9015QU is a battery monitoring transceiver IC designed for 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 improving the availability of the system by a low cost.

It also enables bidirectional information flow by including an error management unit including several inputs and outputs that are programmable on each TLE9012AQU.

Summary of 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)
  • 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
  • AEC-Q100 qualified

Benefits

  • Robust communication without need of transformers or common mode chokes
  • Master-on-Top or Master-on-bottom selectable without tedious configuration
  • Bi-directional communication scheme using error management logic
  • Ring mode topology for further system availability at low cost

Potential Applications

  • Hybrid Electric Vehicle (HEV)
  • Plug-in Hybrid Electric Vehicle (PHEV)
  • Battery Electric Vehicle (BEV)
  • Energy Storage System (ESS)
  • Home Energy Storage system
  • CAV
