MAX14630/MAX14632
USB Charger Adapter Emulators
General Description
Benefits and Features
The MAX14630/MAX14632 are USB adapter emulators
with automatic host charger identification circuitry for
USB dedicated chargers.
S Optimized for Charging Adapters
Flexible Device and Adapter Connection Order
Convenient CB Pin Controls the Charging Mode
The devices allow USB wall adapters, travel chargers,
and other dedicated chargers to identify themselves
as a USB dedicated charger to USB devices, an Apple
charger to Apple products, and a Samsung Galaxy
dedicated charger port to legacy D+/D- short detection
devices that use the D+ pullup of the USB transceiver.
S Faster Charging
Apple 2A Charging Capability in Autodetection
Mode
Samsung Galaxy Tablet 2A Charging Capability
(MAX14630)
S Improved Charger Interoperability
Meets New USB BC Revision 1.2 Specification
Backward Compatible with Previous USB BC
Revisions
The devices feature a control input that allows for charger
mode selection. The MAX14630 supports both Apple 2A
and USB Battery Charger (BC) revision 1.2 specification
compliant devices in Autodetection 2A mode and Samsung
Galaxy Tablet 2A devices in SS 2A mode. The MAX14632
supports Autodetection 2A mode as well as Autodetection
1A mode for compatibility with most Apple and USB BC
compliant devices.
Meets China YD/T1591-2009 Charging Specification
S Greater User Flexibility
CB Pin Controls Charger Mode
S Save Board Space
2.9mm x 1.6mm, 5-Pin TSOT Package
The devices are available in a 5-pin (2.9mm x 1.6mm)
TSOT package and are specified over the -40NC to
+85NC extended temperature range.

Detailed Description
The MAX14630/MAX14632 are USB adapter emulators
with automatic charger identification circuitry for USB
dedicated chargers.
Autodetection
The MAX14630/MAX14632 feature Autodetection mode
for dedicated chargers. In Autodetection charger
mode, the device monitors the voltages at DM and
DP to determine the type of device attached. With the
MAX14630 or MAX14632 in Autodetection mode, when
The devices allow USB wall adapters, travel chargers,
and other dedicated chargers to identify themselves
as a USB dedicated charger to USB devices, an Apple
charger to Apple products, and a Samsung Galaxy
dedicated charger port to legacy D+/D- short detection
devices that use the D+ pullup of the USB transceiver.

or higher, and the voltage at

DP is V

threshold,

Resistor-Dividers
The devices feature internal resistor-dividers for biasing
data lines to provide support for Apple-compliant devices.

Mode Control
The devices feature a digital input, CB, for mode
selection. For MAX14630, connect CB to a logic-level
low voltage for Autodetection 2A charger mode or to
a logic-level high voltage for Samsung 2A charger
mode. See Table 1. For the MAX14632, connect CB to
a logic-level high voltage for Autodetection 2A charger
DP is forced higher than the V
threshold, the internal
DP
switch disconnects DM and DP from the resistor-divider,
and DM and DP are shorted together for dedicated
charging mode.
Once the charging voltage is removed, the short between
DM and DP is disconnected.
