The open-drain outputs include current limiting circuitry, which limits the maximum current each output can sink. As the drain voltage increases, the drain source current decreases. This feature protects the outputs and the components they are driving. At 25°C, the output clamp is typically activated when the drain source current is 250 mA. Thermal protection is also included in the open-drain outputs. As the temperature increases, the output resistance increases limiting drain source current to prevent damage to the output and the components it is driving. At 25°C, the output typically limits the drain source current to 120 mA.
