Abstract
A hysteresis current comparator includes a first current comparison unit, a second current comparison unit, and a control circuit connected to the two current comparison units. The first current comparison unit compares a first reference current with an input current and outputs a first voltage accordingly. The second current comparison unit compares a second reference current with the input current and outputs a second voltage accordingly. The control circuit generates an output voltage according to the voltages output by the two current comparison units, or generates an output voltage according to the voltages output by the two current comparison units and the output voltage of the control circuit at a former state.
