NU1652

概要信息
NU1652 is a highly integrated and efficient wireless power receiver and suitable for up to 70W output power application. It integrates a synchronous rectifier and a programable low drop-out regulator. The regulator can provide a wide range regulated voltage. NU1652 can conduct bi-directional communication with a transmitter system through ASK and FSK. The communication is compliant with WPC. NU1652 can also be operated as a transmitter (Tx) to charge another receiver. Only a few external components are needed and maximum 15W power can be transferred. NU1652’s flexibility is provided by an on-chip 32Bit MCU which can customize and optimize the device for various applications and custom needs. The programmability includes output power, bidirectional communication scheme, system protection, status reporting and error reporting. NU1652 also includes standard protection functions such as input under-voltage lockout, short-circuit protection, over-voltage protection, over-current protection, overpower protection and over-temperature protection. These protections further enhance the reliability of the system solution.
