Introduce
The SC9625 is a high-integrated and high-efficient single-chip wireless power receiver/transmitter IC(RTx). The SC9625 integrates a high efficiency synchronous fullbridge rectifier with ultra-low RDS to convert the AC power signal from a wireless transmitter to DC power and a programmable low-dropout LDO allowing for extremely high efficiency and system optimization. The SC9625 contains an industry-leading on-chip 32-bit MCU with extremely low standby power consumption and MTP memory offering great flexibility for system firmware update. As a receiver, it can deliver 50W(20V/2.5A) output power to the downstream charger system. As a transmitter, it can support up to 15W output power to other wireless receivers. The SC9625 is compatible to WPC Qi (v1.3) protocol and in support for propriety protocols. The device is available in an ultra-small 2.875mm x 4.035mm WLCSP-54 package.
