XT2059 Overview
The XT2059 is charging management circuit that can be programmed through an external resistor constant current / constant voltage charging. The device includes an internal power transistor, does not need external current sense resistor and blocking diode in applications. XT2059 requires minimal external ponents, and meet the USB bus specification, is very suitable for portable applications in the field.
