driving motor with bjt
June 2, 2009
i want to thank every body here for this usefull forum and the great answers i have found.
I want to run applications with PIC MCU but PIC can not sink them(like DC motor).so i need transistor.
but as i look to for example C945 datasheet,the betaof transistor is not specified!!!!!!
only a range is specified for beta.
so how can i have precise design to let my transistor work with the exact CE current I want?????
