The LB and LE are quad push-pull drivers capable of delivering output currents to 1A per channel. See notes mohor for a two Arduino pin solution. Distributor Name Region Stock Min.

So you need to know what motor l293g are going to use before you are designing your electronics. Here you only need to drive one wire, the other can be fixed to GND in this case. You might find out this driver isn’t the best choice for your motor type, or maybe it is.

The motors on the right can turn motot only. A separate supply input is provided for the logic so that it may be run off a lower voltage to reduce dissipation.

Hook up the circuit and run your motor while keeping your finger on the chip. There is an L and an LD part number. Product is in design stage Target: Unsure about whether the L will work with your motor?

MAS3 on May l923b, I would use a BYV27 click! The pinout for the L in the pin package is shown below in top view.

Data sheet PDF fileKb. As far as I know the LD is rated as 0. If you want to control a stepper motor, you need a full bridge per coil pair. Those diodes will from a short circuit to the reversed voltage, but not for the output signal. L notor D is comparable to LB. The L is simplest and inexpensive for low current motors, For high mltor motors, it is less expensive to build your own H-bridge from scratch.

But sometimes you just don’t have a need for a motor to run in 2 directions. If you need to control 2 directions, you need a full bridge. Read times previous topic – next topic.


I mentioned fast diodes, as a lot of people building stuff like this aren’t aware of their existence and purposes. Product is in volume production. Computers and Peripherals Data Center. Not Recommended for New Design.

Both will need external diodes. The LB and LE are package in 16 and pin plastic DIPs respectively ; both use the four center pins to conduct heat to the printed circuit board. You need fast diodes for this, so the short circuit is reached before damage can be done to the transistors.

Yes, pulse width on enable pin can control speed. Most hobby setups with steppers will require 2 full 2l93b, so one entire L, which will probably be the reason for the existence of this package except for the hobby part, very few hardware is produced just for hobbyists.
