The DS2710 is ideal for in-system charging of single-cell nickel metal hydride (NiMH) cells for low-current portable applications. Inputs to the DS2710 include USB voltage sources and 5V regulated adapters. Temperature, voltage, and charge time are monitored to provide proper fast-charging control algorithms for single-cell NiMH or nickel cadmium (NiCd) batteries. The DS2710 includes battery tests to detect defective or inappropriate cells such as alkaline primary batteries.

Applications

  • Battery-Powered Toys
  • Cordless Mouse
  • Small Rechargeable Devices
  • Voice Recorders

Product Detail

The DS2710 evaluation kit (EV kit) demonstrates operation of the DS2710 single-cell NiMH charger IC. The kit includes an assembled and tested PCB with a AA-size battery socket for easy connection to USB or other power source and a CD with documentation for the kit and device. The DS2710 EV kit fully charges a single NiMH chemistry cell and then provides a maintenance charge current to counteract self-discharging. Safety features include overvoltage protection, thermal protection, charge timeout, and alkaline-cell rejection by impedance test. An LED output displays the charging state.

Applications

  • Battery-Powered Toys
  • Cordless Mouse
  • Small Rechargeable Devices
  • Voice Recorders
