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 -40°C to +85°C extended temperature range.
