USB Charger Adapter Emulators

General Description

The MAX14630/MAX14632 are USB adapter emulators

with automatic host charger identification circuitry for

USB dedicated chargers.

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.

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.

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.
