NU8500Q is a highly integrated digital controller for wireless power transmitter compliant with WPC EPP standard. This device and NU80XXQ, the companion power stage ICs, form simple, high-performance and cost- effective wireless power transmitter solutions suitable for a wide range of applications.
NU8500Q integrates all essential functions to deliver regulated power and maintain robust communications with WPC compliant receivers. Used with NU80XXQ, the smallest and most integrated power stage IC, the twochip turnkey design provides the most spacesaving solutions.
NU8500Q also emphasizes on providing reliable and robust charging experience by preventing any transient conditions, such as receiver load variations and Rx/Tx coupling changes, from disrupting communications and continuous charging. The device adopts a proven foreign object detection (FOD) scheme to detect metal objects and prevent harmful heating. The device also integrates the protection features such as over-temperature and over-current protections, input lowvoltage detection and input power limit.
