TPS2546QRTERQ1 is an automotive-qualified USB charging-port controller with an integrated 5 V power switch and USB 2.0 data switching for SDP, CDP, and DCP charging-port designs.

Best for

  • Legacy automotive USB 2.0 charging ports
  • USB ports requiring BC1.2 CDP or DCP support
  • Ports needing integrated VBUS current limiting and fault indication

Avoid if

  • New designs requiring an actively recommended lifecycle status
  • USB SuperSpeed differential-pair switching through the controller
  • Applications requiring more than 2.5 A continuous OUT current

Check before use

  • NRND lifecycle status
  • Current-limit resistor selection
  • PowerPAD thermal layout
  • Required USB data and charging mode
