If +5V power supply ground wire and analog ground wire are in the power supply terminal, the connection point will be connected with power supply, or should near to the OTG13S pins. GND connects with ground wire of metal outer covering to keep the resistance of ground wire lower for a good effect. The position nearing the OTG13S pins is preferable for a better effect. Power supply instructions When need not to support USB mobile hard disk, +5V power supply can use various linear voltage regulators such as 7805, and the current should exceed 300mA. When need to support USB mobile hard disk, it is preferable that +5V power supply adopts switch power supply such as LM2567, current should exceed 800mA, the voltage adjusted is about +5.3V, and it can make sure that hard disk has enough current and voltage. At UPW pin, adding a switch connecting 470R resistance and S8550 in parallel can make the power supply current of USB mobile hard disk higher than 700mA. the power supply voltage range of USB HOST interface is +5V/±0.5V. © 2002-2009 Hard & Soft Technology Co., LTD. http://www.HSAV.com Page 3 of 7 OTG13S User Manual June 10, 2008 LM2576 +5V VIN OUTPUT GND BACK ON/OFF IC1 hsavd221.pdf UPW R1 470 1 2 3 4 5 TR1 S8550 R2 470 R1 330 VIN TR2 S8550 VBUS +5.3V C13 104 D1 RS130LTR L1 100uH/1A Diagram 3, LM2576 typical circuit Diagram 4,the power supply circuit that can apply to USB mobile hard disk Audio Frequency Instructions ± Power supply is the best choice for the sake of a good effect ,if the power supply of the complete machine is ±power supply. Or single power supply can be adopted, and the plus input of operational amplifier connects with 1/2 power supply, as the following diagram 5. If there is no requirement for the sound, operational amplifier is not required and resistor and capacitor filter can be directly applied, as the following diagram 6, but signal output range and high frequency effect may be not good.

Inserting U disk can automatically upgrade program after copying OTG13S.AR5 file in the root directory of U disk, and OTG BIOS can automatically identify new file. If the file in the U disk is identical with OTG13S file, OTG13S program will not be upgraded. OTG13S.AR5 can’t exceed 32K bytes, and upgrading can be finished within several seconds. The electricity supply can’t be cut off bang in the middle of the upgrading.
