MAX14600–MAX14605
USB Host Charger Identification/Adapter Emulators
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.
