Hello
I need to control a motor from 10% to 100%, a voltage of 12v to 16v, nominal 14v, a maximum continuous current of 15A without motor, with a peak with no start of 60A maximum, with a frequency of 10khz. If I have a duty 10%, and current 15A, and if I use a free-wheel diode circuit, I would have a loss p = vd * (1-duty) * Imax, where vd is the diode drop, vd = 0.6, P = 0.6v * (1-0.1) * 15A, I would have a loss of 8.1W, but I have a size restriction and it would be difficult for me to be able to remove all this heat. Then I thought of a synchronous system with two mosfets, Half-bridge driver encounter to work continuously (100%), so I thought of a P and N mosfet, but I did not find a half-bridge driver, I'm probably looking for the wrong terms.
Summary: Is there any model half-bridge driver for mosfet N and P for frequency of at least 10khz?
