I'm looking for a cheap mosfet gate driver for half bridge configuration.
-mosfets to be used for dc motor control
-half bridge topology

Good advice, Chris, and for Mike, read IR's application notes.
Thanks,

IRF does just about every chip, look for the IR21XX type series on IRF website.

TC4427 and non/half-inverting friends.

Depending on your current requirements, the TC/MAX4427 (~$2) or the Infineon TLE5205 are the two I've used (~$4.50). 4427 for motorfaders (~500mA) and the 5205 for small industrial motor control (1-2A).
For general MOSFET driving, the TC4427 is great. However for a 'half bridge' configuration, in the same sort of power range, the IR2181, is my favourite. This generates the voltage to drive one 'high side', and one 'low side' N channel MOSFET, suiting this configuration excellently.
Best Wishes
ST 'L6384'. Very cheap (equiv' $1), 8 pin DIL. Logic input. Fets can be powered anywhere from 16V to 600V. Magic!
