NU1036
NU1036 is a new generation of high integrated efficiency power transmitter power stage, it integrates a full-bridge power stage designed for a wide frequency range, high accuracy current sense and high side driver to drive external FETs. Full-Bridge with adaptive deadtime control makes strong robust and high efficiency. Slew rate control optimizes the low -EMI design. LDO optionally be able to output 4.8V or 3.3V. 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.
