XT2101 Datasheet | Silinktek

Three Function Programmable Constant Current Source - General 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 25mA, to ensure that the chip is not damaged. Meanwhile Chip built-in linear temperature protection, as the temperature rises, automatically reduce the output current to ensure that loss does not...
