Description
Description
The
STUSB4500
is a USB power delivery controller that addresses sink up to 100 W
(20 V; 5 A). It implements a proprietary algorithm to allow the negotiation of a power
delivery contract with a source without MCU support (auto-run mode). PDO profiles
are configured in an integrated non-volatile memory.
The device supports dead battery mode and is suited for sink devices powered from
dead battery state and requiring high power charging profile to be fully operational.
Thanks to its 20 V technology, it implements high voltage features to protect the CC
pins against short-circuits to V
BUS
up to 22 V and to support high voltage on the
V
BUS
pins directly connected to the V
BUS
power path up to 28 V.

Functional description
The STUSB4500 is a USB Type-C™ and power delivery controller IC for sink applications. It is able to negotiate
a power delivery contract with a source without MCU support (auto-run mode). It relies on proprietary algorithms
and configurable PDO (power data objects) thanks to an integrated non-volatile memory. It supports dead battery
mode to allow a system to be powered from an external source directly. Combined with its capability to negotiate
directly a power contract, the STUSB4500 is the ideal controller device for autonomous systems requiring high
power charging profile to be fully operational.
The STUSB4500 major role is to:
Detect the connection between two USB Type-C ports (attach detection)
1.
2.
Establish a valid source-to-sink connection
3.
Determine the attached device mode: source or debug accessory
4.
Resolve cable orientation and twist connections to establish USB data routing (MUX control)
5.
Negotiate a USB power delivery (PD) contract with a PD capable source device
6.
Configure the incoming V
BUS
power path and the charging paths accordingly
7.
Monitor the V
BUS
power path and manage the V
BUS
voltage transitions
8.
Handle the high voltage protections
The STUSB4500 also provides:
Dead battery mode
PDO (power data object) customization through NVM
Internal and/or external V
BUS
discharge paths
Dual high power charging path support
Debug accessory mode detection
Customization of the device configuration through NVM to support specific applications

2.2.1
Pin description
CC1 / CC2
CC1 and CC2 are the configuration channel pins used for connection and attachment detection, plug orientation
determination, USB power delivery communication, and system configuration management across USB Type-C
cable. CC1 and CC2 are HiZ during reset.
2.2.2
CC1DB / CC2DB
CC1DB and CC2DB are used for dead battery mode. This mode is enabled by connecting CC1DB and CC2DB
respectively to CC1 and CC2. Thanks to this connection, the pull-down terminations on the CC pins are present
by default even if the device is not supplied (see
Section 3.5 Dead battery mode).
Warning: CC1DB and CC2DB must be connected to ground when dead battery mode is not supported.
2.2.3
RESET
Active high reset.
