My mistake, I should have mentioned that I currently have the circuit connected to a 12V supply.
OperaHouse, I agree with you. I found that the low-side FET needs to be turned on in order for the high-side output of the same driver to be turned off. So, for example, if Q3 is PWM'd Q1 will no...
Right now all of the inputs to the driver are a logic low, connected to the output of a buffer (74ACT244SC).
The FETs, Q1 and Q2, as well as Q3 and Q4, are FQB55N10. (http://pdf.zener.ru/90581.pdf?datasheet%20Fairchild%20Semiconductor%20FQB55N10TM)
Something else I have noticed is that Vs is...
I would agree, but that doesn't seem to be the issue here. I attempted shorting the High-input to ground, but this did not change the output of the device.

I have designed the attached H-Bridge circuit, but I am having trouble using an IR2181 High/Low Side driver for driving the FETs. Even with nothing on the High-Input of the IR2181, the device is outputting on the high-output and I cannot determine why. Does anyone have any experience with the...
I have the task of going through the lighting technical standards for my company, and I've been focusing a lot on LED lighting.
Everywhere I do research, I get blasted with info on how economical LED lighting systems are. But, when I do a simple calculation, they extra cost of an LED fixture...
