    How Can I Boost the Base Current in a BJT-Driven DC Motor Circuit?

    How to increase the current?! [FONT="Tahoma"][SIZE="4"]I'm designing a drive circuit for a 12V DC motor I'm using a (2N3055 BJT) as a switch to control the output, and I'm using a (74121 monostable oneshot) to control the BJT switch. So, the output of the 74121 is fed into the base of the...

    I need a help designing Motor Driver Circuit

    [FONT="Fixedsys"]I'm designing a driver circuit for a 12V DC motor (Power Window). I'm using an L293D motor driver chip. According to the http://www.zartronic.fr/doc/Z1/L293D_ST.pdf the chip can withstand a supply voltage Vs up to 36V. I'm only using a 9V battery. The circuit and the motor are...
