DESCRIPTION

The SGM41563 is a linear charger for single-cell Li+/ polymer battery plus an ultra-low standby current boost operation for generating a 5V output from the battery power. Its wide input range allows charging with loose regulated power like conducting coil, solar cells or thermal coupling piles. The boost quiescent current (0.68μA TYP) is affordable even for small cell always-on standby application.

The SGM41563 is available in a Green SOIC-8 (Exposed Pad) package.
