Best and Low cost MOSFET Driver IC

[ismu]

Hi

Which one is the best Driver IC among IR2110 , TLP250 .
why the use of isolated Driver [TLP] anything advantage over IR2110?

Its rather better to comment on this if I know the exact circuit you are intending to build using these drivers.

Generally speaking, IR2110 can be used for both hi-side and lo-side mosfets in half H-bridge configuration using bootstraps, i.e. only two IR2110's are needed for full H-bridge. But you need 4 TLP 250 for the same. There are ways to use a TLP250 as hi-side driver also, but it needs a bootstrap circuit similar to IR2110. Moreover, you need to take care of TLP250 maximum supply voltage and maximum gate voltage for the mosfets. A TLP250 can work on higher operating frequencies.
Optoisolators are used for level shifting, protection, etc. I think for most of the purposes IR2110 can be used without optoisolators.

sorry for reply you the above wrong information ,i want to reply you that i think IR2110 is better than TLP250.IR2110 It is a high-pressure and speed functions MOSFET driver, an independent high-end and low-end output drive channel ,it is just like TLP250's upgraded version

You can't really compare bootstrapping drivers directly to optoisolated drivers. Neither is an "upgraded" version of the other. They fulfill two different niches, and generally aren't interchangeable.

If you need a fully isolated gate driver (like for very high power, high reliability applications) then you use one. If not then a bootstrapping driver is probably more appropriate.

for high side TLP Vout=24v ie :Vgs in high side =12v , But in low side TLP Vout=low side Vgs=24v [source as ground ]. is there any issue? because Vgs>12v ,i think it may damage the mosfet ,right?

To know that you need to check the datasheet of your mosfet for maximum gate voltage
