Wireless Charging Transmitter
NU11011
NU11011 is a high frequency, high integration transmitter IC for 1.78MHz wireless charging. NU11011 integrated Boost converter, 32bit 36MHz MCU core, 8KB SRAM and 64KB Flash, and fast charging block PD/BC1.2/QC/FCP/SCP. NU11011 integrates all critical functions of power system, bootstrap circuits for external resonant capacitor switches, 4.8V/3.3V/1.5V LDO and input current measurement. NU11011 integrates input capacitor and snubber. Controllable slew rate/ dead time of gate driver and PWM frequency dither function of TX power FET can further reduce the EMI of power system. NU11011 supports FSK communication, multi channels ASK demodulation, Q factor detection and power loss based foreign object detection. I2C and UART interface are used to communicate with other devices. NU11011 also includes under voltage lockout UVLO, over voltage protection OVP, over current protection OCP and thermal shutdown.
