As is well known, the charging methods for terminal devices are mainly divided into wired and wireless charging methods. Wired charging technology is relatively mature, and wireless charging technology is also flourishing. Nowadays, there is not much difference between wireless charging power and wired charging power, and wireless charging has also freed itself from the constraints of cables, becoming a popular choice for consumers.

Product Introduction

Recently, Nanxin Technology has launched a new 50W highly integrated and efficient single-chip wireless power receiving/transmitting chip - SC9625, with an internal high-efficiency synchronous full bridge rectifier.

SC9625 supports dedicated protocols. Adopting a super small 2.875mm x 4.035mm WLCSP-54 package, it can be widely used in fields such as mobile phones, tablets, medical and industrial instruments.

In wireless charging systems, there are three major systems: input power, transmission, and reception.

The reason why SC9625 is called RTX (Wireless Charging Receiver and Emitter Chip) is because in addition to serving as a 50W wireless charging receiver chip, it can also be used as a wireless charging transmitter by adding a power supply to the output end.

As a receiver, SC9625 can provide an output power of 50W (20V/2.5A) for downstream charger systems. As a transmitter, it can support up to 15W of output power to other wireless receivers.

The SC9625 integrates ultra-low R (on) MOSFETs, which can convert AC power signals from wireless transmitters to DC power, as well as a programmable LDO, achieving extremely high system efficiency. The SC9625 includes industry-leading on-chip 32-bit MCUs with extremely low standby power consumption. Multiple erasable memory provides great flexibility for system firmware updates.
