I'm new to here. I am recently making an H-bridge inverter with IR21531D (here is the data sheet). I connected them this way:
When I measure the Lo and Ho pin with passive probe and differential probe (I only have one differential probe), and I got this I use the differential probe to measure the voltage between Ho and VS, and the Lo and Ho gate signal are overlapped. The dead time is too large which is not even close to the datasheet (0.6 us typ.). If I connect my FET, the circuit will short together.
Can any master here could help me out? Thank you.
