Chrontel’s CH7213A is a low cost USB Type-C logic

controller. The device is targeted for system designers

implementing USB Type-C devices with DisplayPort

capabilities and USB Power Delivery 2.0 support. The

CH7213A integrates the USB Type-C plug orientation

and attached detection mechanism on the CC (Channel

Communication) pins. Its robust Power Delivery 2.0

module using the BMC protocol can enable USB Type-C

devices operating in various power management roles

including Consumer, Provider and Power Role Swap.

The DisplayPort Alt. mode is another alternative interface

supported in the CH7213A. A built-in Billboard Class

can be automatically exposed to the USB 2.0 D+/- bus if a

Type-C PD Source (DFP) does not equip USB Type-C

Alt. Mode features that support DisplayPort signal

transmission. The system with CH7213A’s DisplayPort

Alt. mode enabled can be programmed to support Type-C

to DisplayPort display or DisplayPort to a Type-C DP

Alt. mode monitor. The CH7213A’s bi-directional signal

converter for the DisplayPort HPD (hot plug detection)

and VDM (Vendor Defined Message) is capable of

translating the HPD to the appropriated VDM to Type-C

DP device and vice versa. In addition to hardware

support of PHY and Link layers, the CH7213A has an

internal microprocessor to handle the cable logic

communication and can be programmed for

customization according to the application of USB TypeC platforms.

For reducing the BOM cost of final products, the

CH7213A integrates all necessary components and

circuits, such as LDO, clock generation isolation circuit,

Ra

, Rd and Rp etc.
