## 常見問題 FAQ

- **Who is Power MOS Electronics (PowerMOS)?** Power MOS Electronics Ltd. (擎茂微電子) is a Shenzhen-based IC design company founded in 2006 that specializes in power-line carrier (PLC) LED pixel driver chips, with R&D centers in Taiwan and Belarus. It supplies festive-lighting and smart string-light brands with a complete solution from IC and controller to mass production.
- **What is power-line carrier (PLC) LED pixel control?** Power-line carrier pixel control modulates address and grayscale data onto the power line, so power and control share the same two wires. Every LED bead has its own address and can be set individually, a single failed bead does not take down the rest of the string, and addresses can be written automatically on the production line.
- **How does PLC compare with WS2811 and DMX512?** WS2811-style shift-register LEDs need three wires and pass data bead to bead, so one failure can break the whole string. DMX512 gives every fixture an address but needs five terminals, tops out at 250 Kbps and costs more. Power-line carrier needs only two wires, keeps individual addressing and fault isolation, and fits the classic two-wire string structure.
- **Which LED driver ICs does PowerMOS offer?** Main families: P9864 / P9866 serial-parallel programmable pixel control, P9874 parallel programmable, P9865 / P9873 RGBW four-channel, P9867 / P9868 fixed-address (including the two-section address solution), P9871 dual-layer address for copper-wire lights, the P9831 / P9832 high-refresh series, P9165 single-voltage carrier constant-current driver, P9825 five-channel permanent-light driver and P9779 replaceable-bulb RGBW driver, plus matching controllers. See the Products page for every model.
- **What applications are PowerMOS chips used in?** Christmas string lights, net and curtain lights, copper-wire fairy lights, Christmas trees and 3D motifs, permanent (eave) lighting, replaceable-bulb strings, and decorative installations in malls, theme parks, stages and city lighting where every bead must be controlled individually.
- **How many patents does PowerMOS hold, and how many chips has it shipped?** PowerMOS holds 18 US and EU patents (7 owned + 11 formally licensed), covering camera-based address reading, parallel address detection, high/low-level code reading and more. Cumulative shipments exceed 500KK (500 million) chips, including the P9864 and P9831 / P9832 series.
- **How do I get samples, datasheets or a design recommendation?** Use the IC finder on the Solutions page, or click "Get a Solution" / "Request Samples" to send your requirements online. You can also email sales-02@powermos.com or call +86 755-2320 7019. Technical documents are available on request from our engineers.
