See for example here.call it level translation
Possibly yes, but one will have to know what the max. current of the driving signal is (e.g. PWM1H1). A level shifter's primary purpose is adaptation of voltage levels, not current levels.Does it increase current also?
That is useful link, one further clarification is as per ohm's law if the voltage increases obviously the current should increase. Am i correct?A level shifter's primary purpose is adaptation of voltage levels, not current levels.
How did u arrive at this conclusion? Can you please tell me? Suppose if i design my circuit, what is the parameter i have to look for in the data sheet to find out how much current it draws? In the present data sheet of IR2181, which parameter i have to look for to find out the current it draws? Will it be same under all conditions?Hello,
will not draw many current:
bertus
Most probably also provides more current.So, the main purpose of the IC is it will convert the 3.3V PWM signal to 5V signal. Am I correct? This is called amplification? Does it increase current also?
Yes it does provide more current.
That is valid for resistive loads only. Semiconductors are not resistive loads.per ohm's law if the voltage increases obviously the current should increase. Am i correct?
Sorry Constantin, but this cannot be said definitely. One needs to know the properties of the source of the driving signals (e.g. PWM1H1) to answer this question.Yes it does provide more current.
From above point i assume the ACT is only for level shifting and we are not concerned of the current rating of the ACT, if it can provide minimum current should be fine?Another point: this has nothing to do with the capability of a driver to supply current.
True.You are probably right, but is based on guessing .
