Description

The DPS1035 is part of a family of power switches optimized for the USB Type-CTM and other hot-swap applications. Through the analog interface, exception status is reported and functions like voltage limiting and output voltage ramp-up rate can be programmed.  

This device is designed to operate between 4.5V and 24V. Its built-in fault-handling mechanism includes reverse voltage and current blocking, input over-voltage protection, and thermal shutdown. In addition, the ramp-up time of the output voltage can be adjusted to minimize in-rush current and to ensure system stability. Before any exception condition is notified via the low-active FAULTB signal, de-glitch of 7ms is applied to prevent false triggering.  

The DPS1035 is housed in the low-profile and space-saving V-QFN4040-17 package which is manufactured with environmentally friendly material.
