V1.0 April 2020 Datasheet Ag321T Silvertel 15 Watt Qi compatible Wireless Power Module 1 Features Qi compatible wireless power transmitter for 15W and 5W receiver Backward compatible Silvertels proprietary 15W receivers the Ag320R Low bit rate customer communication(with Ag320R) Foreign object detection Low Standby Current Size 32 mm x 21 mm x 7.2 mm Simple Integration 2 Description The Ag321T is a wireless power transmitter module designed to work with a 15W Qi receiver or the Ag320R to deliver 15W maximum power or backward compatible at 5W with any other Qi compliant wireless power receiver (E.g. the Ag301), typically used in wireless charging applications. With the increased use of mobile & portable devices, the Ag321T wireless power module offer a wide range of benefits: - There are no cables to get tangled and you dont have the problem of having different plugs or sockets for various devices. There is no risk of electrical shock, as there are no exposed metal parts. Can be used in explosive environments as there are no contacts to cause sparks. This means that there is no contact degradation due to friction, corrosion or abrasion. The units can be completely sealed for use in harsh environments, as its operation is not affected by dirt, dust, water or chemicals and can even be used underwater. Can be used in medical environment where disinfecting and sterilization is required. The Ag321T has 3 times the power of standard Qi wireless power making it suitable for higher power applications.
