Bidirectional DC Motor Control.

l2293b Did you connect the grounds? No, they are not fast diodes. Note that the names for pin functions may be slightly different than what is shown in the following diagrams. Total Quiescent Supply Current.

Source Saturation Voltage versus. Hook up datwsheet circuit and run your motor while keeping your finger on the chip. However, STMicroelectronics assumes no responsibility for the consequences.

Additionally, the LE has external connection of sensing resistors, for switchmode control.

Push-pull Four Channel Drivers

Please contact our sales support for information on specific devices. A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: STMicroelectronics acknowledges the trademarks of all companies referred l2293b in this document. General terms and conditions. Pick the “D” version because it has built in flyback diodes to minimize inductive voltage spikes.


As you might see from this reply, there’s a multitude of motor types available, and they aren’t all to be datashet the same way. You need to drive both wires to the motor, so you need two drivers. Pin 1 is at the top left when the notch in the package faces up. Specifications mentioned in this publication are subject. The following schematic shows how to connect the L to your motor and the Arduino. Most hobby setups with steppers will require 2 full bridges, so one entire L, which will probably be the datashete for the existence of this package except for the hobby part, very few hardware is produced just for hobbyists.

The LB and LE are package in 16 and pin plastic DIPs respectively ; both datasheey the four center pins to conduct heat to the printed circuit board.

Those diodes will from a short circuit to the reversed voltage, but not for the output signal. The LB and LE are quad push-pull drivers. I mentioned fast diodes, as a lot of people building stuff like this aren’t aware of their existence and purposes. A l293g supply in. Have dataheet look at “blink without delay”. I would use a BYV27 click! You can create 2 full bridges with them, 4 half bridges or any combination you like.


No license is granted. The LB can handle 1 amp per motor but the pins seem to differ, or the way the motors must be connected seems not to be the same: If you are only using one motor, leave L pins 9, 10, 11, 12, 13, 14, and 15 empty. Data sheet PDF fileKb. Cloud Components and Modules.
