USB Host Charger Identification/Adapter Emulator

Enables Faster Charging of Virtually Any USB-Powered Device

Please check latest availability status for a specific part variant.


The MAX14617 is a third-generation USB 2.0 host charger identification device that combines USB Hi-Speed analog switches with a USB adapter emulator circuit.

The device supports pass-through mode and auto mode. In charging downstream port (CDP) pass-through mode, the device emulates the CDP function while supporting normal USB traffic.

The device also supports charging downstream port (CDP) and standard downstream port (SDP) charging during the active state (S0). The MAX14617 also supports dedicated charging port (DCP) charging during the standby state (S3/S4/S5).

The MAX14617 is available in an 8-pin (2mm x 2mm) TDFN package, and is specified over the -40°C to +85°C extended temperature range.
