L no D is comparable to LB.

Not Recommended for New Design. So you can do with just one driver. Note to ME students: Distributor Name Region Stock Min. I need to control 2 motors and I want to use the 1 amp capable H bridge.

You need to know the motor anyway, because you also need to know the voltage, but more importantly the stall current it will take. Menu Products Explore our product portfolio.

A more recent, improved specification, pin-for-pin compatible chip is recommended for new designs: No availability reported, please contact our Sales office.

I mentioned fast diodes, as a lot of people building stuff like this aren’t aware of their existence and purposes. You might find out this driver isn’t the best choice for your motor type, or maybe it is. Pin 1 is at the top left when the notch in the package faces up. The L is limited to mA, but in reality can only handle much small currents unless you have done some serious heat sinking to keep the case temperature down.


Product is in design feasibility stage. Product is in volume production 1. You can create 2 full bridges with them, 4 half bridges or any combination you like. The motor on the left can be driven to run both clockwise or counterclockwise.

LB Datasheet, PDF – Alldatasheet

The most common method to drive DC motors in two directions under control of a computer is with an H-bridge motor driver. Now, how do I power a L? The PDF shows multiple options in 1 schematic. Free Sample Add to cart.

Please contact our sales support for information on specific devices. Computers and Peripherals Data Center. The L consists of 4 half bridges. You need to drive both wires to the motor, so you need two drivers. The L is simplest and inexpensive for low current motors, For high current motors, it is less expensive to build your own H-bridge from scratch. Here you only need to drive one wire, the other can be fixed to GND in this case. The LB and L2993b are package in 16 and pin plastic DIPs respectively ; both use the four center pins to conduct heat to datasgeet printed circuit dztasheet.

You need fast diodes for this, so the short circuit is reached before damage can be done to the transistors. So then you do not need to use a more complicated way of connecting them.


The LB and LE are quad push-pull drivers capable of delivering output currents to 1A per channel. I don’t understand the schematics in the pdf. Marketing proposal for customer feedback. Media Subscription Media Contacts. If it gets too hot to touch, you can’t use it with your motor.

General terms and conditions. No, they are not fast diodes. Each motor takes 3 Arduino pins.

Push-pull Four Channel Drivers

But sometimes you just don’t have a need for a motor to run in 2 directions. The pinout for the L in the pin package is shown below in top view.

There are motors available that are made to rotate in a specific dataxheet most of those also have a gear attached. The generic 1n diodes aren’t fast and as raschemmel datasheef out will probably not withstand the currents.

Push-pull four channel drivers. MAS3 on May 05, If you want to control a stepper motor, you need a full bridge per coil pair. Support Home Complete list and gateway to support services and resource pools.

The L comes in a standard pin, dual-in line integrated circuit package.
