TPS65982 USB Type-C
®
and USB PD Controller, Power Switch, and High-Speed
Multiplexer
1 Features
• This device is certified by the USB-IF for PD2.0
– PD2.0 is no longer certifiable on new designs
as of June 2020
– All new designs requiring certification should
use a PD3.0 compliant device
– Article on PD2.0 vs PD3.0
• Fully configurable USB PD controller
– Control for external DC/DC supplies through
GPIO
• Ex: TPS65982EVM
– Port data multiplexer
• USB 2.0 HS data and low speed endpoint
• Sideband-use data for alternate modes
– GUI tool to easily configure TPS65982 for
various applications
– Support for DisplayPort alternate mode and
thunderbolt alternate mode
– For a more extensive selection guide and
getting started information, please refer to

3 Description
The TPS65982 device is a stand-alone USB Type-C
and Power Delivery (PD) controller providing cable-
plug and orientation detection at the USB Type-
C connector. Upon cable detection, the TPS65982
device communicates on the CC wire using the USB
PD protocol. After successful USB PD negotiation
is complete, the TPS65982 enables the appropriate
power path and configures alternate mode settings for
internal and (optional) external multiplexers.
The mixed-signal front end on the CC pins advertises
default, 1.5 A or 3 A for USB Type-C power sources,
detects a plug event and determines the Type-C cable
orientation, and autonomously negotiates USB PD
contracts using a Bi-phase Marked Coding (BMC) and
the Physical Layer (PHY) protocol.
