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.


  • Wide Operating Voltage Range: 4.5V to 24V 
  • 1-Channel power switch with built-in fault detection and recovery mechanisms like input under-voltage lockout, reverse-voltage & current blocking, thermal shutdown and input over-voltage protection 
  • RDS(ON) of Embedded Power MOSFET at 30mΩ 
  • Adjustable DV/DT Control at Start-Up 
  • Manual Discharge ON/OFF Control for IN and OUT Ports 
  • Fault Reporting (FAULTB) with Blanking Time at 7ms Typical 


  • Notebook, Desktop & AIO PCs; Servers and Tablets
  • Docking Stations, Universal & Multimedia Hubs
  • FPTVs, PC Monitors
  • Set-Top-Boxes, Residential Gateways, Storage Devices
