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. 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 mode. Connect CB to a logic-level low voltage to place the MAX14632 in Autodetection 1A charger mode. See Table 2. 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 voltage at DM is VDM1 or higher, and the voltage at DP is VDP or lower, the voltage remains unchanged. If the voltage at DM is forced below the VDM1 threshold, the internal switch discon nects DM and DP from the resistor-divider, and DM and DP are shorted together for dedicated charging mode. Similarly, if the voltage at DP is forced higher than the VDP threshold, the internal 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. Table 1.
