科瑞芯电子供应 伏达 NU1680C QFN16 无线电力接收器

Descriptions

NU1680C is a highly integrated wireless power receiver, which requires less quantity of surrounding components compared with NU1610. It gives the benefit of the very low total system cost and less PCB area for wireless power receiver solution. Also, since requires no firmware to program, it will much simplify the design effort and consolidate the solution more easily and quickly. It integrates a synchronous rectifier without bootstrap capacitors designed for a high efficiency purpose and low cost. The regulator can provide a wide range regulated voltage from 3.5V to 9V compliable with different applications. Furthermore, it can regulate the output voltage tracking the battery voltage to further lower down the charging system power loss.

NU1680C can conduct communication with a transmitter system through ASK. The communication is compliant with WPC V1.2.4. FOD parameters can be configured by I2C interface or external resisters to pass the FOD test.

NU1680C also support to be connected to a main AP, communicated by I2C interface. It provides external interrupt, ADC value of battery voltage and output current etc.

NU1680 also includes standard protection functions such as overcurrent protection, short-circuit protection, overvoltage protection and thermal shutdown. These provisions further enhance the reliability of the system solution.

The device is housed in a compact 3.0mm?3.0mm QFN package.

Applications

■ WPC 5W BPP Compliant Receiver with Maximum 5W Received Power

■ Wireless Power Receiver for TWS, Electric Toothbrush, Electric Shaver, ECigarette and others Consumer Equipment
