Abstract:
Apparatus for indicating multiple operating states of a battery charger providing a charging voltage across positive and negative output leads comprising:(a) a dual-color indicator comprising:(i) a first color light emitting circuit having a first sense terminal and a common terminal; and(ii) a second color light emitting circuit having a second sense terminal and a common terminal coupled to said common terminal of said first color light emitting circuit;wherein the light emitting elements of said first and second color light emitting circuits are disposed in adjacent relationship to emit light through a common diffusing lens; and(b) a control circuit having a common terminal coupled to said common terminals of said first and second color light emitting circuits and having first and second charger terminals coupled in series with one of said positive and negative output leads of said battery charger;wherein said first and second sense terminals of said respective first and second color light emitting circuits are coupled to the other one of said positive and negative output leads such that said coupling of said first and second light emitting circuits is operable to apply operating bias to said light emitting circuits.
