USB Type-C Power Delivery Controller
BM92A30MWV
General Description
BM92A30 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.
BM92A30 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.

4.7. Power Supply Management
4.7.1. Outline
This LSI has a power selector. It select the lowest power supply voltage from VSVR, VEX, or VB for low power consumption.
Internal Power Supply (VCCIN) gives priority in order of VSVR, VEX, and VB. VCCIN supplied from the power selector is
used to LSI main power source. LDOs (for internal only) are supplied from VCCIN, and output each internal supply voltage.
Each power supply input have UVLO and OVLO. And POR (power on reset) signal is generated from detection of
LDO28OK, LDO15DOK, LDO15AOK, and VCCIN.
