Features and Benefits

  • Charges Up to 10 NiMH cells
  • Load Detection Allows the Device to Enter Low-Power State
  • dT/dt Charge Termination
  • Monitors Voltage, Temperature, and Time
  • Regulates Charge Current Through Linear or Switch-Mode Operation
  • LED Displays Charge State

Product Details

The DS2715 demonstration board allows the user to explore all features of the DS2715 NiMH charge controller. The demo board is populated for either linear-mode operation or switch-mode operation. The default configuration for the linear mode kit charges a 3-cell stack at an approximately 0.5A charge rate with a 130-minute timeout. The default configuration for the switch-mode kit charges a 3-cell stack at an approximately 1.0A charge rate with a 70-minute timeout.

Applications

  • Handheld Gaming
  • Handheld POS Terminals
  • Portable DVD Players
  • Portable Television Sets
  • Test Equipment
