Description

The DPS1133 is part of a family of power switches optimized for the USB Power Delivery and other hot-swap applications. Through the analog interface, exception status is reported and several functions can be programmed: current limit, overvoltage protection, and output voltage ramping up. The fast role swap function which complies with the requirements defined in the USB Power Delivery Specification Release 3.0, V1.0a is implemented.
