Connect these pins to digital outputs on your robots microcontroller. This will result in the motors stopping slowly and naturally from friction. This included power connectors, diodes, LED indicators, and even a 5-volt regulator. The longer the PWM duty cycle is, the faster the motor will turn. Here are some handy tables to show the various modes of operation. 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.

Moror 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.

All inputs are TTL compatible. This will result in the motors stopping mptor and naturally from friction.

One of the annoying features of the unit is the lack of internal parasitic flywheel diodes to deal with voltage spikes. In the proceeding sections we will connect the LN to a micro-controller to operate a bi-polar stepper motor and explore using pulse-width-modulation PWM to control motor speed on a standard DC motor. 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.

Welcome visitor you can login or create an account. By using PWM, you are turning power on and off very quickly to adjust the speed of the motor. In this series we will explore how to use the LN in a number of actual tested and functioning circuits.

They can be 1N Schottky diodes. 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. As shown in the above illustrations I have redrawn the “multi-watt” package into a more understandable form. If using this material on another site, please provide a link back to my site.

l829 Do not enable the onboard 5V regulator if you plan to supply more than 16V to your motors. An onboard 5V regulator is provided that can be used to power other parts of your robot’s circuitry such as an Arduino microcontroller. Here are some handy tables to show the various modes of operation.

Take care to parallel channel1 with channel 4 and channel 2 with channel 3.

How to use the LN Dual H-Bridge Motor Driver

Otherwise you must input 5V regulated power at pin 5 so that the circuit can operate properly. It is powerful enough to drive motors from V at up to 2A peak.

This is in my opinion the smart way to go to save time, money, and effort. To use the current sense feature, remove the jumpers and attach to the header pins. The two enable pins should be tied together. D1 – D8 are used for this purpose.

When these pins are HIGH, power is output to the motor. Motor Driver Truth Tables Here are some handy tables to show the various modes of operation.

Perhaps an updated mtoor will include these internally. It features a powerful LN motor driver module with a heavy duty heat sink.

Connect these pins to digital outputs on your robots microcontroller. Leave the jumper connected when not using motlr sense. The motors will come to an instant stop.

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 typical robot motor driver for use with two DC motors. This included power connectors, diodes, L2889 indicators, and even a 5-volt regulator. Web site Copyright Lewis LoflinAll rights reserved.
