6 Summary

Powering capacitive loads is a common application where TI’s smart HSSs are used. The main obstacle when driving this type of load is the resulting inrush current. TI’s switches include current limit and thermal protection features to help suppress large inrush currents and create a more reliable system. The current limit threshold and junction temperature can affect the ability of the switch to charge a capacitor. By setting low current limits and at lower temperatures, the amount of capacitance the HSS can successfully charge increases.
