Description
The STUSB1602 is a generic IC designed in a
20 V technology. It addresses USB Type-C™ port
management both on the host and/or device side,
and is suited for a broad range of applications.
The STUSB1602 can handle all functions from
Type-C attach detection, plug orientation
detection, host to device connection, VCONN
support, and VBUS configuration.
It also provides a USB PD TX/RX line driver and
BMC (biphase mark coding) transceiver which
allows USB PD negotiation and alternative mode
through an external MCU.
Additionally, the STUSB1602 provides support for
dead battery operation.
