3-phase brushless motor driver

[kling]

Hi,

I'm currently designing a 3 phase brushless motor driver which consists of 6 power MOSFETS, 6 TTL/CMOS comparators and 6 AND gates. The operating condition of the MOSFETs is Vdss = 75V. I've found the required MOSFET. So, how do i determine what type of comparators should i use (i.e operating condition)? Is there a guideline for me to follow? Please help~~

comparator supply must be highter than 15volts
