PRODUCTION DATA.
The high side and low side MOSFET switches are short-circuit protected with maximum switch current equal to ILIMF. The current in the switches is monitored by current limit comparators. Once the current in the high side MOSFET switch exceeds the threshold of its current limit comparator, it turns off and the low side MOSFET switch is activated to ramp down the current in the inductor and high side MOSFET switch. The high side MOSFET switch can only turn on again, once the current in the low side MOSFET switch has decreased below the threshold of its current limit comparator.
