Hi all,
I want to use this mosfet driver with arduino or other 5V logic IC to driver IRF150 or IRF510. However, once I apply the signal, nothing happen like there is no input signal at all and I can see clearly with oscilloscope the pwm signal is working fine while the output is maintained at the applied voltage.
is there something wrong or the IC is burnt ?
note: I connected the output directly without any resistor or capacitors

JS:
Mosfet drivers usually need two separate rails to provide the floating power for the output of the driver.

Not much right now, but floating mosfet use driver with a secondary power source, for now go to de datasheet to check, when I can I could elaborate a bit more

I am using 12V for the mosfet to drive the load while the mosfet driver is powered via 5V and share same ground
