Weltrend’s USB Power Delivery Controllers Achieve USB-IF Certification
2015-11-27
Weltrend Semiconductor (TAIEX: 2436) today announced that its USB Power Delivery (PD) controller chipsets passed the USB Implementers Forum (USB-IF) certification test for USB Type-CTM DFP (Downstream Facing Port) applications. The Weltrend controllers passed the full set of compliance tests at the recently held USB-IF Compliance Workshop event in Taipei, Taiwan. | |
Weltrend’s USB PD controllers address a broad set of market segments for the emerging USB Type-C products including power adapters for USB Type-C based notebooks, 2-in-1s, tablets, and smartphones as well as USB Type-C based accessories such as docking stations and dongles. | |
The Weltrend USB PD controllers are high-voltage process based and are highly integrated to minimize external components. The controllers integrate USB-PD baseband PHY, Type-C cable detection, shunt regulator, voltage and current monitors, discharge port, MCU and control circuit of blocking MOSFET. | |
An embedded programmable memory is available for program code and user configuration data. An on-chip regulator can operate at single power supply from 4V to 30V. | |
Key features of Weltrend’s USB PD controllers include: | |
● | USB Type-C charge-only Downstream Facing Port (DFP) |
● | USB Type-C Upstream Facing Port (UFP) for dongle applications. |
● | USB Power Delivery Specification Rev. 2.0 |
● | USB Type-C Cable and Connector Specification Revision 1.1 |
● | Built-in shunt regulator and support 5V to 20V VBUS output |
● | Programmable Over Voltage Protection (OVP) and Over Current Protection (OCP) |
● | Low side voltage output current shunt monitor |
● | CPU equipped with program memory and SRAM for the implementation of following features: |
-Power Delivery message protocol and device policy | |
-VBUS output voltage control | |
-Power supply protection | |
● | External blocking MOSFET control |
● | Internal RC oscillator |
● | Internal VDD regulator |
● | General purpose I/Os |
● | Serial interface: I2C and UART |
● | Support power saving mode |
● | Operating voltage range: 4V ~ 30V |
● | Operating temperature range: -20°C ~ +105°C |
