ISL94208EVZ

4- to 6-Cell Li-ion Battery Management Analog Front-End Evaluation Board

The ISL94208 battery management IC is designed for use with a microcontroller and features an analog front-end with overcurrent protection for multi-cell Li-ion battery packs. The ISL94208 supports battery packs consisting of four to six cells in series and one or more cells in parallel.

The ISL94208EVZ evaluation board provides a platform to evaluate the performance of the ISL94208 battery front-end IC. The kit contains the following components:

  • ISL94208EVZ board
  • ISL94208DB1EVZ cell balance daughter board
  • ISL94208DB2EVZ cell balance daughter board
  • GUI software for a PC running Windows XP
  • A power supply interface board for connecting a single power source or a battery stack

Key Features

  • Software selectable overcurrent protection levels and variable protect detection times
    • 4 discharge overcurrent thresholds
    • 4 short-circuit thresholds
    • 4 charge overcurrent thresholds
    • 8 overcurrent delay times (charge)
    • 8 overcurrent delay times (discharge)
    • 2 short-circuit delay times (discharge)
  • Automatic FET turn-off and cell balance disable on reaching external (battery) or internal (IC) temperature limit
  • Automatic cell balance turn off on IC over-temperature
  • Integrated charge/discharge FET drive circuitry
  • Internal cell balancing FETs handle up to 200mA of balancing current for each cell
  • Sleep operation with negative or positive edge wake-up
  • <10μA Sleep mode

Applications

  • Power tools
  • Portable equipment
  • Battery backup systems
  • Military electronics
