i read so many threats here about that topic i'm using IR2110 to drive IRF1405 n-mos channel transistor
i want to know what's value of Vdd ,Vcc , capacitors and resistors shall i use to drive 12v motor
thanks in advance
firstly i'm using different Transistor as i'm using IRF 1405 n-MOS transistor
and the motor that'm working on is 12v DC
so i think value of resistors and capacitors shall be changed also ?
value of load supply what shall i use ?
i tried the circuit today but some thing very strange appeared
as the two upper mosfets worked although i connected HIN and LIN of the reverse direction to ground and LIN of forward direction to Vdd and applied my PWM signal to the HIN of forward direction transistor
note : i'm sure my connection was true but why the IC act like that ?
is there any thing active low in this IC ?
i didn't find any thing like that in the datasheet
There are no identifiers like "forward" and "reverse" in your schematic, may be they are in your head. It would be better if you clearly describe which signals have been applied to which actual circuit pins. I understand that the said drive pattern involves a circuit modification, because the original circuit has only two input signals DRV1 and DRV2.
You should also show which waveforms have been observed to allow others to determine if they are expectable or indicate a wiring fault or part defect,
You should however consider, that if the LIN signal of one bridge side is permanently low (deactivated), the HIN signal has no effect due to missing bootstrap supply.
To comment previous post #4, the Vdd and Vcc supply levels in the original schematic (5V and 12V) are just O.K.
