Abstract
A power switching circuit has high and low side switches (6, 8). The load-side FET (8) has a main body part (30) and a sense FET part (32). The current sensing circuit (32) measured the low side current. A capacitance (56) couples the switch node (10) to a current signal node (52) to provide a combined signal on current output (58), the combined signal including the low side current and timing information.
