The output current of the ATLS500MA104 can be set by an input voltage linearly or modulated by an external signal of up to 4.6MHz in bandwidth, resulting in a minimum 75nS rise and fall times at the output current. The output voltage is 0.5V to 3.6V when powered by a 5V power supply.The controller has temperature compensation network so that the output current maintains the same even as the controller temperature rises.
