Hi

I have some query need your help.

1, Whether to support wireless power supply without battery: There is no super capacitor or battery at the receiving end?

2, Wireless power supply distance: can the distance between the receiving coil and the transmitting coil be 8~13mm?

3, Support small inductance coil: support 0.6uh coil? If possible, how much wireless power efficiency about 8mm~13mm?

4, Can it be applied to three types of medical products? 

Waiting for your reply. 

Thanks

Star

    Hello Star

    1, Whether to support wireless power supply without battery: There is no super capacitor or battery at the receiving end? -- Bill J -- It can be used without a battery but most applications have a power storage device.  Device can only operate when wireless power is present.

    2, Wireless power supply distance: can the distance between the receiving coil and the transmitting coil be 8~13mm? -- Bill J - No, the Qi standard is 5mm and beyond this is difficult at best.

    3, Support small inductance coil: support 0.6uh coil? If possible, how much wireless power efficiency about 8mm~13mm?  -- Bill J- An RX or TX coil of 0.6uH will not work with the TI wireless power devices.

    4, Can it be applied to three types of medical products? -- Bill J - This would be difficult, not possible at this time.
