TPS25821 - USB Type-C 1.5-A Source Controller and Power Switch

Download the TPS25821 datasheet PDF. This datasheet also covers the TPS25820 variant, as both devices belong to the same usb type-c 1.5-a source controller and power switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPS25820/21 is a USB Type-C source controller with an integrated 1.5 A-rated USB power switch.

The TPS25820/21 monitors the Type-C configuration channel (CC) lines to determine when a USB sink is attached.

Key Features

  • 1 USB Type-CTM Rel. 1.3 Compliant Source Controller.
  • STD/1.5-A Current Capability Advertisement on CC Lines.
  • Connector Attach/Detach Detection.
  • Super Speed Polarity Determination.
  • VBUS and VCONN (TPS25820).
