The TLE9009DQU is a multi-channel battery monitoring and balancing IC crafted for Li-Ion battery packs in automotive (MHEV, HEV, PHEV, BEV), industrial (ESS), and consumer applications (e-bike BMS, home energy storage). It handles cell voltage and temperature measurement, cell balancing, and isolated communication to the main battery controller. Moreover, it includes essential diagnostic tools for safety assurance.

Features

  • Balances & monitors up to 9 cells
  • Robust 90V/130nm automotive technology
  • 16-bit delta-sigma ADC for each cell
  • Built-in digital filter (70Hz cut-off)
  • Secondary ADC for E2E safety mechanism
  • Digital stress compensation
  • Infineon CDD compatibility
  • PSOC™ HVPA Pack Monitor compatibility
  • 5 NTC channels + 4 GPIOs
  • UART & capacitive coupled interface
  • Daisy chain communication supported
  • Ring mode communication supported
  • ASIL D BMS safety applications supported

Benefits

  • Infineon tech. and device architecture
    • Best in class Application Robustness
    • Best performance under noise
  • Highly accurate voltage measurement
    • Reliable and precise cell monitoring
    • enables accurate SoC / SoH measurement 
  • Lowest system cost
    • Small package (TQFP-48) for lean PCB
    • Min. amount external components needed
    • High feature integration for lean BOM
