XT2101 Description
XT2101 is a programmable constant current source, through an external resistor to set the output current. XT2101's internal control circuit that can achieve full current, 1 / 4 current and burst flash three functions, three functions controlled by external switch cycle occurs. XT2101 built-in short circuit protection, when IOUT and VDD form a short circuit, the chip will automatically adjust the output current to...
