NCWQ8203/8203A
Application
Automotive wireless power transmitter compliant with WPC Qi2.0 Extended Power Profile (EPP) and Magnetic Power Profile (MPP)
Car in-cabin Wireless Charging
Wireless Charging in Train
NCWQ8203/8203A is a highly integrated wireless power transmitter power stage with peripheral analog circuits that are required to implement a WPC compliant 15W transmitter. NCWQ8203/8203A integrates a full bridge power amplifier with four MOSFETs, the high accuracy current sense and differential voltage sense amplifiers, the multi-channel ASK demodulator, high precision Q detection block, and protection circuits. NCWQ8203/8203A shall be used together with a controller IC in application, the smart power stage can be configured and controlled by serial communication interface.
