SLVSF33A May 2019 – August 2021 TPS65988DJ
PRODUCTION DATA
The figure below shows Dual Port Thunderbolt Notebook application. The TPS65988DJ is capable of managing two full featured Type-C and PD ports supporting USB, DisplayPort, Thunderbolt and PD charging. When the TPS65988DJ detects a connection on a Type-C port it will generate an interrupt to the Thunderbolt controller to generate the appropriate data output. The TPS65988DJ’s two internal power paths provide VBUS which is taken from the System 5 V for Port and will control the external sink path to charge the system through USB PD. The System 5 V will also power PP_CABLE1/2 on the TPS65988DJ to supply VCONN to Type-C e-marked cables and Type-C accessories. An embedded controller EC is used to communicate to the TPS65988DJ for additional control and to relay information back to the operating system. An embedded controller can control additional features such as entering and exiting sleep modes, changing source and sink capabilities depending on the state of the battery, UCSI support, control alternate modes, and so forth.
