The MIC4608 features a 450ns propagation delay including a 200ns input filtering time to prevent unwanted pulses. The low-side and high-side gate drivers are independently controlled (with shoot thru protection).
I have bought 4 N-Channel MOSFETs to build an H-Bridge Motor Driver.My Motor drive and my power supply voltage is 12v.My TTL logic voltage is 5v as I want to speed up/down the motor with uC PWM.Now I have understood that I have problem with driving High Side MOSFETs as their Gate Voltage must be bigger in respect to their Source voltage.What are my options now? shall I change them to P-Channel MOSFETs?

$begingroup$Check out this device.
It's a high side N-channel MOSFET driver. I think that it has a little boost converter internally. We've just started playing with these and it will drive the MOSFET gate to 20 VDC with a 12 VDC supply. Nifty huh?!?
Though the device isn't fast, relatively speaking, so you would be better off doing PWM for speed control on the low side MOSFET. You can get a regular FET driver to do this with your 5 V input.

$endgroup$$begingroup$For half bridge just use one of these: -
For full bridge use two. These devices are able to drive n channels topside because they smuggle a bit of energy away from the output using a capacitor $C_{BOOST}$. The 1N4148 is for startup I believe.
There are other devices that can do this too.

$endgroup$$begingroup$This is entirely possible but you need some way to generate the higher-than-supply gate voltage required by the high-side MOSFET. There are several possible ways of doing this:
- Generate this high side voltage from a separate source, using something like a sub-US$0.1 chip like
MC34063
connected into a small boost converter. This method works with any drive waveform - Use a gate driver chip like the sub-$1
IR2110
. This requires a PWM drive waveform as it generates this high voltage using a bootstrap process (essentially a switched capacitor synchronous charge pump)

$endgroup$$begingroup$You should Use IR2101, Its a half bridge gate driver IC with all the details mentioned inits datasheet. Its very useful.try it.
