MAX14640–MAX14644/MAX14651
USB Host Adapter Emulators
General Description
The MAX14640–MAX14644/MAX14651 are next-genera-
tion USB 2.0 host charger adapter emulators that com-
bine USB Hi-Speed analog switches with a USB adapter
emulator circuit.
The MAX14640/MAX14651 feature an I2C 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.
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 I2C
to support various dedicated charger modes such as DCP,
Apple 1A/2A forced, or Apple 1A/2A automatic mode.
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).
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.
