Hi. I'm new to the forum. Here's my hello to everyone and first question. Hopefully someone has a minute to help. ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I'm building a DC motor controller. I've considered an mcu for the front end but I don't have the space in my head to learn the programing. I've searched high and low for a dedicated PWM IC and for the life of me I can't find ANY that can do 100%. They all have built-in deadtime for push-pull smps ect. I can't believe it doesn't exist. Heck, even my cordless drill can do 100%. Here's a few requirments.
Will run off +15vdc
Output capable of 0-100%
2 error inputs
5v internal ref would be a plus.
The only thing close so far is an SG3524 or SG3525 with the outputs tied but they can't do 100%. I also found the TL1451 but the outputs need pull-up resistors and I can't risk any power-on spikes at the outputs.
Any suggestions?
