The MAX14600–MAX14605 and MAX14618 are third-gen-

eration 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/MAX14618 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/MAX14618 support remote wake-

up in standby mode. The MAX14602/MAX14605 offer

backward-compatible CDP emulation upgrade to the

MAX14566E.

The MAX14600–MAX14605/MAX14618 are available in

an 8-pin (2mm x 2mm) TDFN package, and are specified

over the -40NC to +85NC extended temperature range.
