MAX14640–MAX14644/MAX14651

USB Host Adapter Emulators

General Description

Beneﬁts and Features

● Improved Charger Interoperability

The MAX14640–MAX14644/MAX14651 are next-generation

USB 2.0 host charger adapter emulators that combine

USB Hi-Speed analog switches with a USB adapter

emulator circuit.

• USB (CDP) Emulation

• Smart CDP

• Foolproof CDP

• Meets New USB Battery Charging (BC) Revision

1.2 Speciﬁcation

The MAX14640/MAX14651 feature an I C interface to fully

configure the charging behavior with different address

options. The MAX14641–MAX14644 are controlled by

two GPIO inputs (CB1/CB0) and support USB data and

automatic charger mode. In charging downstream port

(CDP) pass-through mode, the devices emulate the

CDP function while supporting normal USB traffic. The

MAX14641/MAX14642/MAX14643 have a CEN output

for an active-high CLS enable input, and the MAX14644

has a CEN output for an active-low CLS enable input to

restart the peripheral connected to the USB host.

• Backward-Compatible with Previous USB BC Revisions

• Meets China YD/T1591-2009 Charging Speciﬁcation

• Supports Standby-Mode Charging for Apple BC

Revision 1.2 Compatible Devices

● Provide Greater Application Flexibility

• I C Controls Multiple Modes (MAX14640/MAX14651)

• CB0 and CB1 Pins Control Multiple Automatic and

Manual Charger States

● Enhance Performance with High Level of Integrated Features

• Supports Remote Wakeup

The MAX14640–MAX14644/MAX14651 feature 2A high-

current autodetect mode. The MAX14641 features 1A

high-current forced mode instead of regular DCP mode.

The MAX14640/MAX14651 can be configured through I C

to support various dedicated charger modes such as DCP,

• Low-Capacitance USB 2.0 Hi-Speed Switch to

Change Charging Modes

• Automatic Current-Limit Switch Control

• ±15kV ESD Protection on DP/DM

● Minimize PCB Area

Apple 1A/2A forced, or Apple 1A/2A automatic mode.

• 2mm x 2mm, 8-Pin TDFN Package

All the devices support CDP and standard downstream port

(SDP) charging while in the active state (S0) and support

the dedicated charging port (DCP) charging while in the

standby state (S3/S4/S5). All devices support low-speed

remote wake-up by monitoring DM, and the MAX14642

also supports remote wake-up in sleep mode (S3).

Applications

● Laptop/Desktop Computers

● USB Hubs

®/

● Universal Chargers Including iPod /iPhone iPad

The MAX14640–MAX14644/MAX14651 are available in an

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

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

Ordering Information and Typical Operating Circuit appear
