Excuse me, light coupling saturation voltage is what mean? According to the comparison of triode, should be just and the IF, temperature, but many unexpectedly also mentioned on the manual IC

Recently is studying optical coupling circuit and application, for VCE and the parameters of the IC is particularly important, especially the application of light coupling output with a hysteresis comparator, can refer to https://mp.csdn.net/console/editor/html/107058384

CodePudding user response:

Look from the curve of the temperature and voltage curve seems a little tend to be linear, as measuring temperature is to research?
Use light coupling the first concern is luminous tube pressure drop, the second concern current ratio, is used to design the circuit parameter,

CodePudding user response:

My understanding is that the light coupling loss can be equivalent to a model of triode, light-emitting diodes, signal as the base level signals so that it can be the equivalent of the triode saturated pressure drop,
