L289 MOTOR DRIVER

Note that “forward” and “backwards” refer to the direction of the motors themselves. By using PWM, you are turning power on and off very quickly to adjust the speed of the motor. Welcome visitor you can login or create an account. Do not enable the onboard 5V regulator if you are supplying more than 16V to motors on pin 3 or the regulator will burn out. The current sense pins in general can be tied to ground, but one can insert low value resistor, whose voltage reading is proportional to current.

Otherwise you must input 5V regulated power at pin 5 so that the circuit can operate properly. This is in my opinion the smart way to go to save time, money, and effort. All inputs are TTL compatible. The motors will come to an instant stop.

Do not enable the onboard 5V regulator if you are supplying more than 16V to motors on pin 3 or the regulator will burn out. If using this material on another site, please provide a link back to my site. Here are some handy tables to show the various modes of operation. This part seems to be the favorite of hobby robot builders.

I have used more common 1N rectifier diodes and they seem to work fine. An onboard 5V regulator is provided that can be used to power other parts of your robot’s circuitry such as an Arduino microcontroller. In the proceeding sections we will connect the LN to a micro-controller to mitor a bi-polar stepper motor and explore using pulse-width-modulation PWM to control motor speed on a standard DC motor.

In this series we will explore how to use the Notor in a number of actual tested and functioning circuits. Internally the LN consists of four independent power amps with 5-volt digital inputs and four high current, high voltage power amplifiers capable of driving single DC motors, and both unipolar and bi-polar stepper motors. The four amplifiers are usually used in pairs forming an H-bridge to switch polarity for to control the direction of a single DC motor or as two pairs of H-bridges a bi-polar stepper motor.

The current sense pins in general can be tied to ground, but one can insert low value resistor, whose voltage reading is proportional to current.

As shown in the above illustrations I have redrawn the “multi-watt” package into a more understandable form. Notor use the current sense feature, remove the jumpers and attach to the header pins. This completes our introduction to the LN dual motoe bridge driver. Perhaps an updated mohor will include these internally.

One of the annoying features of the unit is the lack of internal parasitic flywheel diodes to deal with voltage spikes. This will result in the motors stopping slowly and naturally from friction. Note that “forward” and “backwards” refer to the direction of the motors themselves. Usage Follow the steps below to configure the motor controller board to work as a motod robot motor driver for use with two DC motors.

Refer to the details below. The longer the PWM duty cycle is, the faster the motor will turn. It is powerful enough to drive motors from V at up to 2A peak. Motor Driver Truth Tables Here are some handy tables to show the various modes of operation.

Mohor two enable pins should be tied together. Shown in figure 3 the power amps have connected in parallel for double the power at the cost of operating one bi-directional load such as a DC motor.

When these pins are HIGH, power is output to the motor. This included power connectors, diodes, LED indicators, and even a 5-volt regulator. Do not enable the onboard 5V regulator if you plan to supply more than 16V to your motors. Basic circuit configuration LN. Leave the jumper connected when not using current sense.
