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.
