NU10300
NU10300 is a high integrated efficiency power transmitter power stage, it integrates a full-bridge power stage designed for a wide frequency range (up to 2.0MHz), high accuracy current sense. Full-Bridge with adaptive deadtime control makes strong robust and high efficiency. Slew rate control optimizes the low -EMI design. VDD supply is able to output 4.8V by LDO to drive the external MCU. The proprietary current-measurement circuit provides an accurate current signal to MCU used for the FOD (Foreign Object Detection) power measurement without extra sense resistor. It also includes protection functions such as input under-voltage lockout, over-voltage protection, over current protection, and thermal shutdown. These provisions further enhance the reliability of the total system solution.
