If you are only using one motor, leave L pins 9, 10, 11, 12, 13, 14, and 15 empty. As you might see from this reply, there’s a multitude dztasheet motor types available, and they aren’t all to be powered the same way. Bidirectional L293bb Motor Control. High Voltage Inhibit Current. However, STMicroelectronics dwtasheet no responsibility for the consequences. Now, how do I power a L?

The L is an integrated circuit motor driver that can be used for simultaneous, bi-directional control of two small motors. You can create 2 full bridges with them, 4 half bridges or any combination you like.

Here you only need to drive one wire, the other can be fixed to GND in this case. Fast diodes like the 1N or the 1N?

So you can do with just one driver. See notes below for a two Arduino pin solution. I did link these Shottky diodes: Product is in volume production only to support customers ongoing production.

I mentioned fast diodes, as a lot of people building stuff like this aren’t aware of their existence and purposes. Low Voltage Input Current. l293n

Assume you have only one motor connected with the enable tied to Arduino Pin 3, and the two direction controls tied to Arduino Pins 4 and 5. Product is in volume production Evaluation: The motors on the right can turn clockwise only. During soldering the pins temperature must not exceed ? So then you do not need to use a more complicated way of connecting them. Additionally, the LE has external connection of sensing resistors, for switchmode control.

Each channel is controlled by a TTL-compatible logic input and each pair of drivers a full bridge is equipped with an inhibit input which turns off all four catasheet. The LB and LE are quad push-pull drivers. Product is in volume production. L no D is comparable to LB.

Sink Saturation Voltage versus. Media Subscription Media Contacts. Limited Engineering samples available Preview: Specifications mentioned in this publication are subject.

Communications Equipment, Computers and Peripherals. Selectors Simulators and Models.

Low Voltage Inhibit Current. Storage and Junction Temperature. Each motor takes 3 Arduino pins.

LB – Push-Pull Four Channel Drivers – STMicroelectronics

Menu Products Explore our product portfolio. Data sheet Datasheft fileKb. As far as I know the LD is rated as 0. You need fast diodes for this, so the short circuit is reached before damage can be done to the transistors.

You need to drive both wires to the motor, so you need two drivers. No commitment taken to produce Proposal: Quiescent Logic Supply Datasheft. The L comes in a standard pin, dual-in line integrated circuit package.

MarkT Brattain Member Posts: Pin 1 is at the top left when the notch in the package faces up. Dxtasheet 3 motors are shown connected to the IC, and why only one of them has arrows pointing both directions? 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: Total Quiescent Supply Current.

Both will need external diodes. Product is in ll293b stage Target: The LB and LE are quad push-pull drivers capable of delivering output currents to 1A per channel.
