Any L293D Alternative?! L293D has a huge votlage-drop

Hi, I see that L293D has a huge votlage-drop and as im ot able to include big batteries in my project i just decided to get another controller, whats a good cheap one?! that has like 0.5V max dropoff?! is that cheap to achieve?

Pololu has a good collection of modern motor and stepper drivers: Pololu - Motion Control Modules

All of them work better than the ancient L29x series.

Avoid darlington drivers - any MOSFET H-bridge will perform far better, but they are
nearly all surface mount devices.

The LMD18200 is quite good but not cheap - can mount on heatsink.

i actually have limited options, i couldn't find either of the drivers you listed, how can i choose between the options i have? what should i look for?! one of them says: L298N Dual H Bridge

N/A

The classic Darlington H-bridge chips are L293D and L298. They are both ancient
designs, but they are cheap and available in through-hole packages. They work
well in 24V up designs where the voltage drop becomes a small proportion of the
losses. For lower voltages MOSFET bridges are best.

Can you can parts from Pololu, they do breakout boards for many MOSFET H-bridge
chips for various voltages and power levels.

I can't find any, let me give you a list of drivers available here!

L298N Dual H Bridge
TB6560
DRV8825
SC_20500
IBT-3 H-Bridge 50A
IMS-2B H-Bridge 50A/0V-15V
L298P
Monster Moto Shield VNH2SP30
L298N
L9110S
VNH2SP30 full-bridge
MiniMoto DRV8830
BTN7971B
Reprap-A4988

Anything that is MOSFET, not the L293 / L298's, and not stepper drivers like
the A4988, DRV8825
(unless you want to drive a stepper).

You haven't said what motor(s) you want to drive yet. That affects the choice.

so i guess i can decide myself, my motors are 3-6v thats all i know :slight_smile:

Ok others are really expensive so i just decided to get an more powerful battery :expressionless:
thanks for help :slight_smile:

You also need to find out the stall current for the motor at the voltage you intend to run it at; this too will affect your choice on a driver, as it must be able to support at least the stall current (and ideally, 10-15% more).
