GENERAL DESCRIPTION
XT2102'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. XT2102 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 exceed the package chip power consumption to allow the scope to provide a high reliability protection.● Package
