I want to drive my bipolar stepper motor at higher amp, I got the tip to use "high side h bridge driver" for N-Mosfets. I googled about "high side h bridge driver". But could not find any. Please suggest me some "high side h bridge driver" to run at 15 volt.
 

Many High side drivers are available.
search from the portal such as mouser & digikey with mosfet driver ic search.
Surely you will find it easily.
 
Hi

The phrase "high side H bridge driver" makes no sens.

There are high side switches
There are low side switches
Combine both and you have a half bridge
Combine two half bridges and you have a full bridge = H bridge

There are driver ICs to drive the switches (bjt base or MOSFET gate)

Drivers are availabe for*
* Low side switches
* high side switches
* half bridge (= low side + high side)

What exacely do you need?

Every H-bridge has two "high side" and two "low side"
FETs (or other, but most commonly). An H-bridge driver
IC will control all 4 with some anti-shoot-through
goodness in most cases.

But a stepper motor has usually 4 phases (?) and
would need 2 H-bridges (if phase pairs, antiparallel
is the drive scheme) - 2 drivers, 8 FETs, plus odds
and ends like bootstrap caps one per leg, decoupling
and so on. Phase control happens upstream.

But this can all be found in integrated stepper motor
drivers, if you need less than maybe 5-10A per phase.
Integration slurps up the cost of the external FETs
and makes the total BOM cost cheaper for any
project that the part can handle.
