Times thinking is a technology innovation company, its latest wireless charger, using a micro-high-performance MOSFET This year's release of the Apple iPhone 8, the official push wireless tuyere.
Wireless charging in the past only a small part of the phone only support this year, Apple's 3 new machines all support wireless charging, showing Apple's determination of universal wireless charging.
We all know that Apple's iPhone handset shipments are great, and domestic manufacturers will follow up on mobile phones to support wireless charging receiver, which for the entire wireless charging industry market is a very big positive.
Understand through the dismantling of the charging head network, Baseus think of the latest wireless charger using micro-high-performance MOS. This wireless charging board is composed of four MOSFET H bridge driver by the wireless charger internal controller control, Driving four MOSFETs changes the direction of the current in the transmitting coil to generate electromagnetic waves. The receiving end of the mobile phone receives the electromagnetic waves for wireless charging.
This means that every wireless charger, even with only one coil, requires four MOSFETs to drive, and multiple coils require more MOSFETs to drive.
The tiny WSP4884 integrates two MOSs in a traditional SO8 package, requiring only two tiny WSP4884s to form a complete coil drive, which provides the highest possible power density in a harsh footprint and is now available in wireless Chargers more and more thin and light requirements.At the same time the micro-WSP4884 using advanced high-density technology, similar products to provide relatively small Ciss and RDSON.
