PI5USB8000Q USB Power Switch with Pericom's FAST Charger Circuitry for DCP, CDP, and 2A iPad support Features Description ÎÎAEC-Q100 qualified Type A USB connectors are found in 100% of PCs as well as in wall chargers that are shipped with all of the latest popular hand-held devices that require charging. All of the connectors physically look the same, however, their behavior is different. When a user tries to connect an iPAD into a notebook USB port vs. a USB charger that came with the iPAD, one can instantly observe a different behavior. This is because the communication protocol of a standard PC USB port vs. a dedicated Apple-iPAD USB port is different and it is this communication that enables the iPAD to charge efficiently. The same can be seen by other popular phones and tablets. ÎÎUSB charger controller that supports SDP, DCP and CDP per USB BC 1.0, 1.1, and 1.2 specfication ÎÎDCP (Dedicated charger port) is used when enumeration is not available ÎÎCDP (Charging downstream port) is used when enumeration is available and FAST charging is requested ÎÎSDP (Standard downstream port) is used for systems with standard USB host ports ÎÎSupport for YD/T-1591(Chinese Telecom Standard) ÎÎSupport for non-standard charging such as Apple-1A and There are Apple-1A modes of communication, Apple-2A modes of communication, communication described by the Chinese Telecom standard, YD/T-1591, and communication described by the USB Battery Charging Spec. In order to support all popular phones, all communication protocols must be supported. Apple-2A ÎÎIntegrated 85mΩ MOSFET with thermal and Short-circuit protection ÎÎAdjustable Current Limit from 1.1A to 2.8A ÎÎSingle Power Supply, 5V +/-5% ÎÎFast response time for over-current detection, 4us (typ) Pericom’s PI5USB8000Q is able to offer anybody designing a USB port meant to charge external devices with all communication protocols in a single IC. The PI5USB8000Q can detect the communication language required and then automatically enable charging to occur with different external USB devices.

This feature can help save system power when nothing is connected externally. Using Pericom’s PE/ open drain output flag, the system could disable higher current supplies when no external device is connected. Once an external device is connected, Pericom’s PE/ output flag can inform the system and then in-turn, the system could enable the higher current power supply to enable charging. Next, the Pericom device will detect what type of device is plugged in (BC1.0 device vs. BC1.1 vs. BC1.2 device vs. Apple device vs. YD/T 1591) and then we will automatically switch to required communication mode to properly communicate with the device to initiate charging. Finally Pericom will continue to monitor Vbus for over current scenarios and over temperature scenarios and at the same time we will also detect D+/D- load for plug-out detection. Please note, Plug in detection ONLY works when device is in sleep and charge mode. 7.2 Plug out Detection Once plug-out is detected, then PE/ will once again be pulled high (through external pull-up) and current sensing will resume to determine if a device is plugged in or not. When plug-out detection is not working, PE/ is always pulled high through external pull-up. Plug-out will not work if sleep and charge is not enabled. 7.3 Mouse/Keyboard pass through mode Since USB1.1 devices do no integrate charging protocols, there is no special charging mode required to support charging the device. Therefore, if a USB Low-Speed external device is detected, then Pericom’s solution will simply connect D+/- from the USB connector directly to the USB host controller. The detection process for mouse/keyboard will occur ~1.8 seconds after the Pericom solution enters DCP/auto detect with USB/keyboard pass through enabled mode, which is when CTL1 = 0, CTL2 = 1, and CTL3 = 1. If a low speed device is detected as "attached" at that point, then the pass through mode will be enabled and D+/-P will connect to D+/-H. If the mouse/keyboard is disconnected, while the Pericom's PI5USB8000Q remains in the 011 mode, the device will enter auto-charging mode and will enable the PE/ output pin to detect if an external device is connected or not. Only in auto-charging mode does Pericom ensure all external battery powered devices will succesfully charge. 14-0009 4 www.pericom.com05/08/14 PI5USB8000Q USB Power Switch with Pericom's FAST Charger Circuitry for DCP and CDP support 7.3.1 System wake-up via external mouse or keyboard Today’s systems are enabled to wake up from S3 mode if a pre-enumerated mouse/keyboard has activity (movement or key-pressed). In order for the system to continue supporting this feature, the USB host controller must be able to communicate with the external device in S3 mode.

The Pericom device will continue to monitor D+ for primary detection and then respond with an acknowledgement on D- (with proper timing) to initiate CDP charging to occur. For secondary detection per the Battery Charger 1.2 spec, Pericom will allow the GND signal from 15Kohm pull-down in the USB controller pass through to the port. Therefore when the cell phone sends 0.6V signal on D-, it will see a GND signal on D+, which will provide a VALID response for CDP, secondary detection. Once CDP communication has been initiated by external device, the Pericom IC will provide the acknowledge command without affecting USB signal integrity. This acknowledge command will let the external device know that the USB port (Charging downstream port) can support a minimum of 1.5A (per the USB1.2 battery charging spec). The user can set two current limit values, and then by using ILIM_SEL, the user can switch between which limit they would like to use. Charging Downstream Port (CDP) is the communication protocol found in high charging PCs. These connectors allow USB data to be transferred between the CDP and the external device as well as allow charging to occur up to a max of 1.5A. The actual current draw is managed by the external device, the CDP only limits the max current draw from 1.5A. The communication protocol of CDP is described in the USB Battery Charging Spec revision 1.2. Pericom is able to support this communication. SDP Standard Downstream Port (SDP) is the communication protocol found in traditional USB connectors in PCs. These connectors allow USB data to be transferred between the SDP and the external device as well as allow charging to occur up to a max of 500mA. The communication protocol of SDP is described in the USB2.0 and USB3.0 specifications from the USB organization. Maximum Ratings (Above which useful life may be impaired.
