TG0803 Wireless Charger Module Specifications Module launch synopsis： Transmitter Module for wireless charger is a transmitter designed specifically for non-QI standard wireless reception requirements. The module doesn’t meet WPC1.1standard. Using chips from Shenzhenheshen Technologies Co Ltd, it has advantages of Stable performance, and low power consumption, etc. The unique PWM modulation mode is adopted that transfer efficiency get markedly improved. The convenient of wireless can easy implementation, module output efficiency is high, compared with the wireless Built-in transmitting power and wireless receiving power, it can control the loss of emission energy more accurately. The number of module components is small that have high performance cost ratio, after the debugging can implement “install and play”. This can easily satisfactory the various demands of customers, and it’s perfect for doesn’t meet QI standards for various types of wireless charging equipment. For instance：used in Bluetooth devices with wireless charging function、table computer、electric toothbrush、cosmetic instrument、waterproof electronic equipment、electric automobile, etc. this IC can drive up to 10KW power, at present. ONE.

Module working description 1：Put the tablet PC near the center of the transmitter coil , the green LED on the module will light up, the tablet PC should have voltage and current input, the green LED light is stand for charging. 2：When the module is energized, the blue light and green light are lit for a second and then the blue light goes off and starts charging, The green light keeps on and the blue light goes off, put a foreign body, the blue light was flashing. 3：If the tablet PC is far away from the center of the module，the module doesn’t enter the charging state。LED in blue light illuminated steady state. at this point, you need to move the tablet PC back to the module launch center, the module will automatically enter the charging state. IV 4：If the module detects an exception on the tablet PC receiver, The module will stop working, at this point, you need to move the tablet PC away from the launch, put the tablet PC on the launch module again to enter the charging state. SEVEN．The usage environment of wireless charger A. LAUNCHING BASE 1、The principle of wireless charging is to convert direct current into electromagnetic field, and then send the electromagnetic field up. The general launch distance is 2-7MM. Left and right deviation center point can’t exceed 7MM, the received current will be small or can’t establish a direct connection if more than 7MM. 2、The conversion efficiency is low when the distance is offset, under normal circumstances, the current received by the vertical offset of 1MM is reduced by 100MA, the current received by a lateral offset of 1MM is reduced by 150MA, efficiency will also drop below 70%. 3、Strong magnetic interference, please make sure there is no magnet within 20mm of the surrounding environment. The transmitting power will be reduced if there exist a magnet, this will directly affect the use effect。 4、Metal interference, please don’t allow metallics on the surface of the launch base, the metal on the base must dig a hole that is 15mm greater than the radius of magnetic separator of the transmitting coil if it can’t be avoided according to the structural requirements. This is to prevent electromagnetic fields from cutting meta, it causes abnormal operation of the transmitting base and power loss. V 5、Other terminal devices are placed on the TG0803 wireless charging base, there are different responses depending on terminal equipment, the device on the phone type will display the charge icon, but there is no current input. Some devices are placed on the launch base will be directly identified as foreign matter, at this point, the launch base will directly enter the foreign body protection state, and the blue light flashing. B. RECEIVING CIRCUIT 1、Both the receiving coil and the circuit are built into the tablet PC, try not to charge the TG0803 with…
