DS2712 Datasheet (ds2711 / Ds2712) Loose Cell Nimh Chargers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-5826; Rev 4/11 GENERAL.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The DS2711 and DS2712 are ideal for in-system or stand-alone charging of 1 or 2 AA or AAA NiMH “loose” cells.

Temperature, voltage, and charge time are monitored to provide proper fast-charging control algorithms for nickel metal hydride (NiMH) batteries.

Battery tests are included to detect defective or inappropriate cells such as alkaline primary batteries.

Key Features

  • Charge 1 or 2 NiMH Cells.
  • Detect and Avoid Charging Alkaline Cells.
  • Precharge Deeply Depleted Cells.
  • Fast Charge NiMH with -∆V Termination Sensitivity of 2mV (typ).
  • Monitor Voltage, Temperature, and Time for Safety and Secondary Termination.
  • Regulate Charge Current: Linear Control (DS2711) Switch-Mode Control (DS2712).
  • Drive pMOS or pnp-Type Pass Element or Switch, or an Optocoupler.
  • Compatible with Popular Optocouplers and Integrated Primary-Side PWM Con.
