that first thing i knew those existed, gate emitter capacitance, did not know what it was called till now, but i was only trained with basics for transistors, i find it hard still to ID with data sheets, and there are only few values which i know to look for, usually max power out!, which is why i bench them every time, originally i was testing with pwm, more specifically square (k)hz waves, but then i found the dc flow works better,.
but by what you are saying am i understanding that i will create myself a heat problem from improper saturation?
i would rather use this since the motors are all 6v, but then PIC can do 12v bursts, i have put in V-divider to analog input so PIC can monitor volts, and has control of the 30v driver, and also temperature monitor on transistor, i fear pwm will not give me an accurate reading at gate, and motors would throw off emitter voltages,no? also if i am to drive motors with pwm i would prefer to do it at each independent bridge.
so when you are asking about a load you are referring to what is after the emitter, i thought r3 was the feedback,
after my emitter the transistor will be feeding 4 h-bridges two are 2.5 amp motors, while the other 2 prolly add up to 100ma, all are 6v rated, but all these are another board with another uC as the main computer which feeds data to the 1st PIC which is actually the power circuitry board which is what im working on now.
having said all that , the circuit is my main power supply, it is powered by bench for now, 14v, but will be transitioning to a 11.1 battery, which is why my numbers may have been a bit high, it passes through an 11v feed to 2ESC motor controllers, supplies 5v(7805) for computers, the power line for my 6v motors which we are discussing, and some leds.
