Hi
I'm trying to make a DC motor driver by usnig IR2113 gate driver IC.
is it possible to drive a full H-bridge with IR2113?
thanks.
 

Hi,

Its a general question...and I don´t know what you specifically mean.

You surely read the datasheet.
Then you saw, that the difference between IR2110 and IR2113 is the max. power high side voltage.
Because you choose IR2113 I assume you work with voltage above 500V. (be careful with those high voltage!!)

About "full bridge":
Did you look into a single "full bridge" design to see how it works?
Try it on your own: just do a small hand sketch how you decide to connect a full bridge with IR2113.
After it - if there are still exist some doubts - please feel free to to ask a "specific" question.

My answer: It depends on what you really want. So: yes and no.

Hi
Thanks for your reply Klaus.
I attach my schematic below, I am trying to drive a DC motor by using an analog voltage input. i use NE555 to generate 50% pulse and then by RC network i convert it to traingular waveform. the i use LM324 to compare this waveform with analog input to generate PWM signal. i use IR2113 for gate drive of n-channel mosfet. when i change analog voltage inuput the DC motor speed remain constant, is there any problem in my circuit?
 

No schematic attachment, unfortunately.
I have attached the file.

HIN must be driven by complementary LIN signal (possibly with dead time). HIN is not correctly connected.
 

Hi
Thanks for your response FvM, I changed my circuit and connect HIN and LIN complementary:

How can i make dead time?
 

Hi,

How can i make dead time?
This question is not new.

Therefore, if you do a search in this forum you find 500 threads.

I assume every mosfet manufacturer and mosfet driver manufacturer has related documents...
