Sadly I cant take the credit.

The idea was originally suggested by Melanie but it stuck in my mind because I have an device that uses the HPWM to generate an IR carrier which I then gate with a transistor. Too late to change my existing design but I will use the comparator to do the gating in a later revision of the board.

Not only does it save a transistor and a couple of resistors but has a better voltage swing as well!
