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.

The DS2711/DS2712 support series and parallel

topologies, with independent monitoring and control of

each cell. Charging of NiCd chemistry cells is also

supported.

FEATURES

Charge 1 or 2 NiMH Cells

Detect and Avoid Charging Alkaline Cells

Precharge Deeply Depleted Cells

Fast Charge NiMH with -

ΔV 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 Controllers

Small 16-Pin SO or TSSOP Package

APPLICATIONS

Desktop/Stand-Alone Chargers (AAA/AA)

Digital Still Cameras

Music Players

Games

Toys
