USB Type-C Power Delivery Controller
BM92A14MWV-Z
General Description
BM92A14 is a full function USB Type-C Power Delivery
(PD) controller that supports USB Power Delivery using
base-band communication. It is compatible with USB
Type-C Specification and USB Power Delivery
specification.
BM92A14 includes support for the PD policy engine and
communicates with an Embedded Controller or the SoC
via host interface. It supports SOP, SOP’ and SOP’’
signaling, allowing it to communicate with cable marker
ICs, support alternate modes.
