描述 Description

NU1628 is a highly integrated and efficient wireless power receiver and suitable for up to 30W output power application. It integrates a synchronous rectifier and a programable low drop-out regulator. The regulator can provide a wide range regulated voltage. NU1628 can conduct bi-directional communication with a transmitter system through ASK and FSK. The communication is compliant with WPC.?NU1628 can also be operated as a transmitter (Tx) to charge other receivers. NU1628’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. NU1628 protection includes standard such as input under-voltage lockout, short-circuit protection, over-voltage protection, over\u0002current protection, over-power protection and over-temperature protection.
