When a load switch is used for the external sink path there are a few parameters to consider. Choosing a load switch that is capable of withstanding 20 V on VBUS could be considered as a minimum requirement as some faulty or “out of spec” chargers can have 20 V on VBUS without PD communication. The load switch must be able to handle the current supported in the sink capabilities of the system. A system that can sink up to 5 A and is connected to a source that is capable of 200% Ioc may see up to 10 A current for a duration of time. The load switch used must be able to handle these current spikes when a system supports high Power Delivery currents. Reverse current protection is very important when there are two sink paths used in the system. The two load switches must prevent a low impedance path from VBUS1 to VBUS2 when they are enabled/disabled.
