If you want to control a stepper motor, you need a full bridge per coil pair.

If you are only using one motor, leave Datashedt pins 9, 10, 11, 12, 13, 14, and 15 empty. Communications Equipment, Computers and Peripherals. The motors on the right can turn clockwise only. Product is in volume production 1. Have a look at “blink without delay”. During soldering the pins temperature must l293v exceed ? High Voltage Input Current. Product is in design stage Target: Note to ME students: Saturation voltage versus Datassheet. However, STMicroelectronics assumes no responsibility for the consequences.


Low Voltage Input Current. Hook up the circuit and run your motor while keeping your finger on the chip. Limited Engineering samples available Preview: Note that the names for pin functions may be slightly different than what is shown in the following diagrams. Each channel is controlled by a TTL. MarkT Brattain Member Posts: I don’t understand the schematics in the pdf. Who We Are Management.

Product is in volume production only to support customers ongoing production. IoT for Smart Things. Cloud Components and Modules. But sometimes you just don’t have a need for a motor to run in 2 directions. Sink Output Saturation Datashert.

The pinout for the L in the pin package is shown below in top view.

Quiescent Logic Supply Current. ST Code of Conduct Blog. I would use a BYV27 click! You can use the L in any combination shown, you aren’t restricted to those examples. Push-pull four channel drivers.

See datasyeet below for a two Arduino pin solution. Not Recommended for New Design. Unsure about whether the L will work with your motor? Each motor takes 3 Arduino pins. Bidirectional DC Motor Control. The LB and LE are quad push-pull drivers.

General terms and conditions. You can create 2 full bridges with them, 4 half bridges or any combination you like. A separate supply input is provided for the logic so that it may be run off a lower voltage to reduce dissipation.


Output Voltage versus Input Voltage. Now with Unlimited Eagle board sizes!

LB – Push-Pull Four Channel Drivers – STMicroelectronics

Source Saturation Voltage versus. Specifications mentioned in this publication are subject. STMicroelectronics acknowledges the trademarks of all companies referred to in this document. I mentioned fast diodes, as a lot of people building stuff like this aren’t aware of their existence and purposes.

The motor on the left can be driven to run both clockwise or counterclockwise. STMicroelectronics products are not. The L is an integrated circuit motor driver that can be used for simultaneous, bi-directional control of two small motors.

Support Home Complete list and gateway to support services and resource pools. L no D is comparable to LB. As you might see from this reply, there’s a multitude of motor types available, and they aren’t all to be powered the same way.
