Re: Help with IR 2110
Hi,
You don't need to level shift the input, necessary level shifting is done inside IR2110. As already mentioned by Mr.Davood, you can remove Q3 and all associated circuit, connect input directly to pin 1 of the inverter circuit. Also, your transistor circuit does not provide +/- 5V levels, it gives only a 2V high and a resistor pulled down zero levels. The Hi and Li signals need be only inverted TTL signals for your circuit connection and not level shifted.
Also V11 voltage source is not required.
The pin numbers of 2110 are still not correctly marked so that if there is a mistake in connection, it will not be clear to us.
