I'm trying to identify a damaged IC in my son's radio controlled car. It's SO-8 package, I think it's an H Bridge. The part number starts "CP21" but the last characters are not legible.
There is a photo here:

Pins 1 & 2 are logic level controls for forwards and backwards.
Pins 3 & 4 go to the battery -ve & +ve terminals respectively.
Pins 5 & 6 go to one side of the motor; pins 7 & 8 to the other.
Thanks for any help.
Gareth.
