Advantages of 13.56 MHz (NFC) Wireless Charging
for Compact Device under 200mW
Save the space for charging
"No constraints on design" of devices
Compared to the charging from a USB connector, the conventional charging method for compact devices such as wearables, the wireless charging system equipped with LAPIS Semiconductor's 13.56 MHz (NFC) wireless charging chip set, "ML7630/7631", can save the space for charging function.
Using an ultra-compact antenna as well as an antenna for NFC communication simultaneously can reduce the implementation area down to "about 50%" for compact cube antenna, and "about 75%" for a flexible antenna.
When compared to other charging systems, the 13.56 MHz (NFC) wireless charging that can use ultra compact antennas offers more "compact implementation".
