If I change the resistor to higher datashwet, like ohm. I wonder may be this IC is not suitable for continuous drive. You either drop volts across a limiting resistor or across the chip. What I means is the motor oscillating in forward and reverse direction, and I measured the current thru a DVM connecting is serial with the resistor.
Control of DC Motor Driver – Help Yanco, I think before much more time is spent head scratching trying to understand what you have and what you are doing, you need to tell us something about the motor. We call this ‘dead-time’. I have try to eliminate the 10 ohm by connecting a wire but it burn out the B IC. There is not enough energy to drive the motor. The reason for the difference is when the motor is loaded it droops in speed.
Prev Next Motor driver ICs. A resistance range of 3X10 is recommended Power supply filtering capacitor. If you have one, put a scope CD1 and CD2 and find out what they are doing. So, for our understanding, tell us what you have connected to pin Place as near as possible to the V pin.
Why the design of the BA was in such a way?? Yanco, I think before much more time is spent head scratching trying to understand what you have and what you are doing, you need to tell us something about the motor.
I’ll read the complete data sheet and see what if I can figure it out. The motor revolving speed can be set arbitrarily by controlling the volt- age applied to the motor.
There are no circuits built into these ICs that datasueet vent in-rush currents. The Resistor connected to the BA is 10 ohm 5 Watt.

If no scope at least a volt meter. I doubt your motor has a resistance than high but this should give you an idea of what the motor would see at zero speed. OK, let me tell all the information: No wonder it is hot. Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. I means one of them will have 3 V, one of them zero, and vice versa.
When the motor is running in just the forward direction, how much current does it draw? Even use for 0. CD1 and CD2 are oscillating when motor forward and reverse. Therefore Kv is probably close to However for bi-directional operation, you must have a plus and minus supply. I understand that when changing logic modes the driver should go through ‘open’ mode briefly.
As a general rule, size the wattage of the resistor to twice your calculated watts. The motor resistance is 12 ohm when I measured. Two logic inputs allow four out.

Lastly, when you measured the. Also from datashert data sheet, the can supply 2. Be sure to confirm that the back-rush voltage will not adversely affect the operation of the IC.

I have try placing it vertical far from the PCB and using 50 ohm 5 Watt, it is also very hot. Two logic inputs allow four out- put modes: Perhaps your motor is undersized.

In a very very very quick read of the data sheet, it appears Rc is used to limit current for the unit if the output is shorted.

I would run it in one direction and not reverse it, then measure the current. Refer to my post to Schwarz to see how the motor should be behaving.
With my VR set to min ie, 0.
