Abstract
The present invention relates to a Digital Addressable Lighting Interface (DALI) interface and a power device comprising the same. The present invention can provide a DALI interface comprising: a first limiting circuit unit for outputting a limited current based on a DALI transmission signal and a DALI reception signal; and a gate drive circuit unit for generating, based on the limited current, a drain-source voltage that is used for generating a DALI signal in accordance with the DALI standard. As a result, the present invention can generate a signal complying with the DALI standard even under various voltage and current conditions of a DALI master.
