R-EN & L-EN pins are used for speed control using PWM.Generally, these 2 pins are connected together to a PWM pin of Arduino.R PWM & L PWM pins can be pulled HIGH or LOW to enable Direction of Rotation.The naming convention is bit confusing.Don’t pulse the enables and hold the PWM inputs at a DC level.To get the Motor to move in an H-bridge the Enable inputs should be held high and PWM-A and PWM-B should be different polarity.Current Limitation : The current in the bridge is measured in both switches, High and Low side.If the current reaching the limit current the switch is deactivated and the other switch is activated for a certain time.Over temperature leads to a shut down of both output stages. Over temperature Protection: The BTS 7960 is protected against over temperature by an integrated temperature sensor. If the Supply voltage drops below 5.4V, The Motor driver will switched Off, And won’t turned on untill the Supply voltage increased to 5.5V Or more. Under voltage Shut Down: To avoid uncontrolled motion of the driven motor at low voltages the device shuts off. Then restart when it cools and the Enable line is pulsed low then high. You cannot overload the BTN7960B to destruction.PWM-L: for controlling motor LEFT direction.PWM-R: for controlling motor RIGHT direction.EN-L: PWM Signal for controlling motor speed – Inverse rotation.EN-R: PWM Signal for controlling motor speed – Straight rotation.IS-L: Input signal for detecting high current – Inverse rotation.IS-R: Input signal for detecting high current – Straight rotation.In this post we will be using a huge current Motor 24v 250Watts like this :Ī separate power source is required for this Motor.Ģ4v 10Amp Metal SMPS is used for this source This module can be used to drive 2 wire huge current Motors. This contains one P- channel high side MOSFET and one N channel low side MOSFET with
