LX2206ILD数据手册集成电路（IC）的电池充电器规格书PDF

描述 Description

The LX2206 can be used with a wall adapter or USB power source to charge a single cell Lithium Ion or Lithium Polymer battery. There are two logic selectable and program-mable charge current levels which can be set from anywhere between 50mA to 1A. The termination current is 1/10 the charge level set by the High Level Programming Current Pin. Power status indicators (STAT and DCOK) can be configured to show charge in progress, battery fully charged and external power on. The STAT pin is capable of sourcing or sinking 10mA. The DCOK output is an open drain output. The LX2206 enters a low quiescent current sleep mode when power is removed or when it is logically shutdown to minimize battery drain. There are several protection features which include: under voltage lock out, inrush current limiting, reverse current blocking on the IN pin, a thermal loop to reduce charge current to maintain a low die temperature, an unsafe battery temperature charge inhibitor, and conditioning mode is provided for deeply discharged batteries.  ROHS, PB Free
