Hello guys. I'm using a L293D IC to drive a 12V DC motor, and making it run, I measured a tension drop of about 2V in the motor.
The tension sent from the battery was 12.10V and the tension acting on the motor was 10.38V exactly. Is there any way to reduce this tension drop?
Thanks for the help! =)
You could use a MOSFET-based driver instead of the BJT-based L293D. What you are observing is normal. Each BJT inside the L293D "steals" a little bit of voltage, more formally, it has a voltage drop across the collector-to-emitter junction.
There's not much you can do about it in the L293D other than use a slightly higher voltage to compensate.

Hmm I see! Unfortunatelly I don't have time to learn about it now hahaha
But thanks for the help! =)
