reagrding IR1167 subcircuit

[amitesh43]

hi
i am trying to understand subcircuit of IR1167 in the first attachment and second datasheet so that i can try to design that schematic in LTspice

there is a component called as oneshot or MOT(minimum ON time) block
what i can use in the place of that block

I would think the MOT could be simulated with a one-shot circuit (such as using a 555) and perhaps some logic gating.

 

[amitesh43]

can i use monostable multivibrator in the place of one shot...

 

[FvM]

can i use monostable multivibrator in the place of one shot...

The terms aren't but synonyms.

 

[amitesh43]

ok
but which pin of these should i consider for MOT if i use 555
trigger or discharge,threshold pins

 

[crutschow]

You use the other pins to configure the one-shot configuration such as here. The output pin of the 555 would be the one-shot signal.

ok what kind of driver do i need to use as per the sub-circuit in ir1167 data sheet.
like whether i need to use regular driver or i need some kind of amplifier as in sub circuit of ir1167 in the data sheet
