Toshiba is almost %100 efficient, no cooler at 2–2.5A, way ahead than any other thing for such currents. So cheap and as a kit perfect to use daily everywhere by youth. One handy short current topology makes it killer because it is stackable as paralel. You can easily do 100A box without a fan or cooler. It will drive not only step motors etc but everything by totempole, high-low current signalisation, a tiny led, wify BT driver, anything in a safe children’s control box. It will be 17to24 channels lpt breakout with fast optos + for arduino io + for general purpose multy channel voltage current controllable io box, supply box, fed from xl4015s, giving %50 duty at 80khz, fast enough high quality switching for my son and for childrenand for controllers.
Constructing this by arduino is too slow by high side sense kits for 12 output channels. Fast fuses are never close to such speed and is not suitable for wide current band. I examined all of pdfs, not practicle. l293 with short protection mentioned at application notes is good only under 300mA total current, otherwise around %40 efficiency in reality is out of sense, a too old ic. Lm138 current limiting per toshiba kit just for a channel is not practicle and again, can create efficiency and heat problem for more than 500mA in closed box.
There could be short protection ic, having [(high side sense for hbridge)+(fast multiplexer)+(adc)+ (its own fast clock)+signal out for each channel and or'ed common signal out]. So what can i use for high side fast short protection or is there any Toshiba specific way, what can I do? Thank You.
