STUSB1602QTR USB Type-C™ Power Delivery (PD) Controllers
STMicroelectronics' STUSB1602QTR USB Type-C power delivery controllers protect devices from electrical hazards
Combining low power consumption with robust, high voltage capability, the STUSB47 series and STUSB1602 USB Type-C PD controllers autonomously support full USB PD negotiation. Manufactured using ST’s high performance analog CMOS process, these ICs offer built-in overvoltage protection up to 22 V for the configuration-channel (CC) lines and up to 28 V for the high voltage pins to prevent damage in the event of accidental short-circuit to VBUS.
The STUSB1602 can manage USB Type-C ports in power sources or devices. On-chip CC control logic manages the entire connection setup including selecting the VBUS default, medium-current, or high-current mode. In addition, the device integrates a protected and programmable 600 mA VCONN power switch to support accessories and active cables. The STUSB1602 also implements a USB PD physical layer (including a biphase mark coding IP) to support power-delivery software stack implemented by an external MCU. The hardware and the software is USB PD 2.0 certified both as a sink and a source. Furthermore, it is compatible with USB PD 3.0 core features and most options. The STUSB1602 supports accessory modes and dead-battery mode.
