The MAX1925/MAX1926 feature two precondition levels to restore near-dead cells. The devices source 4mA to a cell that is below 2V while sourcing C/10 to a cell between 2V and 3V. Full charge current is then applied above 3V. A C HG output drives an LED to indicate charging (LED on) and fault conditions (LED blinking). The MAX1925/MAX1926 are available in a 12-pin 4mm 4mm thin QFN package and are specified over the extended temperature range (-40C to +85C). An evaluation kit is available to speed design.
