Description

The STUSB4500 is a USB power delivery controller that addresses sink devices. 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 VBUS up to 22 V and to support high voltage on the VBUS pins directly connected to the VBUS power path up to 28 V.

2.2.1 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.

2.2.4 I²C interface pins

Table 3. I ²C interface pin list

Warning: ADDR0 and ADDR1 pins must be connected to ground when there is no connection to an MCU.

2.2.5 DISCH

This input/output pin can be used to implement a discharge path for highly capacitive VBUS line on power system side.

When used as input, the discharge is internal and a serial resistor must connected to the pin to limit the discharge current through the pin. Maximum discharge current is 500 mA.

The pin can be also used as an open drain output to control an external VBUS discharge path when higher discharge current is required by the application, for instance.

The pin is activated at the same time as the internal discharge path on VBUS_VS_DISCH pin. The discharge is activated automatically during cable disconnection, transition to a lower PDO voltage, hard reset and error recovery state. The discharge time is programmable by NVM (see Section 5 Start-up configuration).

All voltages are referenced to GND.
