The F75204 support most of the USB Battery Charging Specification worldwide, including BC 1.2, Apple® charging spec (for i-Pad & i-Phones) and specs for Samsung Galaxy Tab. The F75204 also equipped with a control output to control peripheral power components. A digital input CB is able to control the mode configuration of F75204. In transmission mode, the F75204 acts like a USB bridge which connects the route between the USB Host and the USB Device, and allows device using CDP mode to charge the handheld devices; in the charger mode the F75204 can automatic detect the device and provide correct acknowledge signal to the device that is going to be charged, even if the computer system has been shut down. By setting the USB Data pins (D+/D-) to the required voltage levels, the charging device recognize the voltage levels, and starts to draw the current to charge. The F75204 are equipped with a control output (CEN or CEN#) allows users to control the peripheral power management device which controls the charging current. The F75204 Series enhanced ESD protection up to ±8kV on the DP and DM. The F75204 is available in a MSOP-8 Package and is allow working over the 0°C to +70°C temperature range. 2 Feature List 4.5V~5.5V Single Supply Operation.

Users can alternate between modes by a digital input mode control pin – CB. In the transmission Mode, as it shows below in Figure 6.1, the F75204 acts as a USB bridge which connect the D+/D- data line of the host to the USB device. In Charger Mode, the F75204 supplies the voltage to the D+ and D- lines from the internal resistor-divider. If the device attached is BC 1.2-compliant, the F75204 will automatically shorts D+ and D- data line to allow correct charger detection. 3 Dec., 2011 V0.16P F75204 F75204 CEN(#) / CEN(#)_Strap Figure 6.1 Pass-Through Mode F75204 CEN(#) / CEN(#)_Strap Figure 6.2 Charger Mode (Auto Detect Mode) Table 6.1.2 Truth table of CB CB Configuration Charger Mode 0 Pass-Through 1 4 Dec., 2011 V0.16P F75204 6.1.2 Advance CDP Function The F75204 featured an Advance CDP function to provide an always USB connectivity for handheld devices. When non-CDP devices are connected to a CDP USB port, some might fail to make connection with the USB host on a standard CDP port. To solve this problem, the Advance CDP feature is able to switches the charging port automatically to SDP mode during handshaking, if the attached device is a non-CDP device. This function can ensure a correct data connection when non-CDP device is plugged in. CDP is the abbreviation for Charging Downstream Port, which allows supported devices to do fast charging (Maximum 1.5A) & data communication at the same time. The advance CDP solution is able to disable CDP function while attached device is not support CDP function, and re-connect to the attached device. 6.1.3 Full / Low Speed USB Devices Wake up Traditional USB host charger may cut off the data linking path then disable the keyboard / mouse wakeup function. To avoid the situation, the F75204 allows Full / Low speed USB devices to wake up the system. In order to make sure the wake up function work properly, the F75204 won’t cut off the D+ / D- data path of USB if the device attached is an full / low speed USB keyboard / mouse. This feature allows most of keyboard / mouse to wake the system up normally. 6.1.4 External Chip Enable Signal – CEN (or CEN#) The F75204 is equipped with a digital output signal pin – CEN (or CEN#), which allows users to control the external power switch. To reduce the complexity, Fintek made this F75204 to supports both active high / low types of power switch. Using an external strap resistor to deiced the character of this pin. Table 6.1.3.1 describes the configuration of strap resistor. CEN Strap CEN CEN# Table 6.1.3.1 CEN(#) Strapping Configuration Remark External Pull-High High Active System External Pull-Down Low Active System In order to control the Power Switch, the CEN (or CEN#) should be connected to the enable pin of the Power Switch. The F75204 will assert a signal for 1 sec to cut off the Vbus power, when the logic input signal level of CB changes from 0 to 1 or 1 to 0. This function is able to emulate the replug of USB device and guarantee that the device has correct contact detection. The F75204 use CEN(#) pin to reconnect the devices. In other word, when a non-CDP device is connected to the USB charging port, the F75204 will trigger CEN (CEN#) pulse, and make the device to reconnect with host in the SDP mode. CEN: (External Pull-High on CEN(#)_Strap) If the USB Vbus is controlled by an Active-High power switch, strap the F75204 to CEN configuration. Then F75204 CEN pin will assert a constant high signal to enable the Vbus Power Switch. Only when the logic level CB changes, then the CEN pull-down for 1 Sec to temporary shut down the Vbus. 5 Dec., 2011 V0.16P F75204 CB Figure 6.1.3.1 CEN Timing diagram CEN#: (External Pull-Down on CEN(#)_Strap) If the USB Vbus is controlled by an Active-Low power switch, strap the F75204 to CEN# configuration. Then F75204 CEN# output signal will keep low to enable the Vbus Power Switch. Only when the logic level CB changes, then the CEN# output signal will assert high 1 Sec to temporary shut down the Vbus. Figure 6.1.3.2 CEN# Timing diagram ※ Please Note that. The CEN(#) signal is designed to provide the correct contact detection after each mode transfer. Please note that all the mode transformation of USB port process must be finished during the work period of the CEN(#) pulse. If the mode transfer process is taking longer than 1 sec please consider to extent the CEN(#) pulse time. 6 Dec., 2011 V0.16P F75204 7 Electrical Characteristics Absolute Maximum Ratings PARAMETER Voltages Referenced to GND SYMBOL VCC, TDP, TDM, CB, DP, DM, CEN Continuous Current into Any Terminal ※ Maximum junction temperature (plastic package) ※ Maximum storage temperature RATINGS UNIT -0.3 to 6.0 V ±30 mA Tj +150 °C TSTO -65 ~ +150 °C +260 °C ※ Maximum lead temperature (soldering 10s) Note: If ICs are stressed beyond the limits listed in the “absolute maximum ratings”, they may be permanently destroyed.
