ANX7402
ANX7402
USB Power Delivery PHY with Channel Configuration Control
Overview:
ANX7402 is a USB Power Delivery (USB-PD) PHY with an On-chip Microcontroller (OCM). The OCM enables ANX7402 to manage the cable detection, USB Power Delivery negotiations, Vendor Defined Message (VDM) communication protocol, and other functions, as defined in the USB Type-C™ v1.1 and USB Power Delivery v2.0 specifications. ANX7402 supports a Hot Plug Detect (HPD) input pin and converts the HPD signal over the Configuration Channel (CC) to enable DisplayPort™ (DP) Alt Mode applications. When paired with a DP-to-HDMI/VGA bridge (such as the ANX7737/9837) and a USB Billboard device IC, the ANX7402 creates an ideal solution for USB Type-C (USB-C™) dongle and docking station applications.
