The DS2715 is well suited for cost-sensitive charger applications where the battery pack is either internal or external to the application. It has been optimized for safe and reliable charging of 1 to 10 NiMH cells in series. The internal gain block can be selected as either a comparator or transconductance amplifier for charge current regulation. This makes the DS2715 configurable as a switched DC charger, a linear current regulator, or a switch-mode current source. The DS2715 pre-conditions severely depleted cells before entering full charge mode. It terminates full charge using the dT/dt technique, which requires an external sensing thermistor. Over-temperature, under-temperature, and over-voltage detection prevents charging under unsafe conditions. A user selectable charge timer allows charge rates from 0.167C to 2C. FAST-CHARGE, TOPOFF and DONE modes are included for highly reliable, safe charging of NiMH cells. Discharge mode allows the DS2715 to enter a low power sleep state while the cell pack is being discharged.

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 Detail

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
