The controller is capable to drive external power MOSFETs for load currents up to 10 A. A current limitation feature is included, it is done by measuring the voltage over the high-side switch (when switch is closed) in Rdson-configuration or by including a shunt resistor above the high-side switch in Shunt- configuration.
