using MC33151 with Arduino

[hussamaldean]

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

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

could you please elaborate ?

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

the driver doesn't work with a supply voltage of 5V, since it has an undervoltage lockout of 5,8V. Also it doesn't make much sense to supply it with 5V - then you could drive the fet directly with logic output of the mcu.

you can simply take a logic level fet and spare you the driver

I scraped the idea of using mosfet and mosfet driver and used L293D instead and it does work wonderfully
