3 Description
The TPS65981-Q1 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 TPS65981-
Q1 device communicates on the CC wire using the
USB PD protocol. When cable detection and USB PD
negotiation are complete, the TPS65981-Q1 device
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 provides
default (900 mA), 1.5-A or 3-A current for Type-C
power sources, detects a plug event and determines
the USB Type-C cable orientation, and autonomously
negotiates USB PD contracts by adhering to the
specified biphase-marked coding (BMC) and
physical-layer (PHY) protocol.
