MAX14600–MAX14605

USB Host Charger Identification/Adapter Emulators

����������������������������������������������������������������� Maxim Integrated Products 1

General Description

The MAX14600–MAX14605 are third-generation USB 2.0 host

charger identification devices that combine USB Hi-Speed

analog switches with a USB adapter emulator circuit.

The devices support pass-through mode and auto mode.

In charging downstream port (CDP) pass-through mode,

the devices emulate the CDP function while supporting

normal USB traffic. The MAX14600/MAX14603/MAX14605

have a pFET open-drain output (CEN), and the MAX14601/

MAX14604 have an nFET open-drain output (CEN) to

restart the peripheral connected to the USB host.

All the devices support the CDP and standard down-

stream port (SDP) charging during the active state (S0)

and support the dedicated charging port (DCP) charg-

ing during the standby state (S3/S4/S5). The MAX14603/

MAX14604/MAX14605 support remote wake-up in stand-

by mode. The MAX14602/MAX14605 offer backward-

compatible CDP emulation upgrade to the MAX14566E.

The MAX14600–MAX14605 are available in an 8-pin

(2mm x 2mm) TDFN package, and are specified over the

-40NC to +85NC extended temperature range.
