BA6219B DATASHEET PDF

Dikasa 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. All other trademarks are the property of their respective owners. I means one of them will have 3 V, one of them zero, and vice versa. How to measure the ohm of the motor I am driving? The VR max voltage is 5V, to turn the motor, 0. Pin CD1 and CD2 are tied to ground with capacitors of ceramic 0.

Tadal Copy your embed code and put on your site: That means the volts available to motor is I means one of them babb have 3 V, one of them zero, and vice versa. Pin 5 and Pin 6 is used to change the direction of the motor. I would double check your wiring of the circuit and measure the ohms of the datasheeet you are trying to drive. When you are switching the directions, how fast do you switch them? This is crazy, because 20 watt resistor will be damn big.

BTW, 50 ohms also get too hot. OK, let me tell all the information: Do I understand this correctly, you are telling the motor to go only forward but it goes both forward and reverse? I made a stepper motor Perm magnet drive long time back.

Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. Anyone experience any driver IC for continuous drive for 10 hours a day? If so at high speed? You either drop volts across a limiting resistor baab across the chip. The VR max voltage is 5V, to turn the motor, 0.

Or are you using logic to turn it on forward and reverse? Defense manufacturing is all about project manufacturing and project accounting. The Eng-Tips staff will check this out and take appropriate action. I have try to eliminate the 10 ohm by connecting a wire but it burn out the B IC. Average watts got reduced.

Are you an Engineering professional? As a general rule, size the wattage of the resistor to twice your calculated watts. The resistor is overheat.

Place as near as possible to the V pin. And bbab the resistor is 10 ohm must be there, the current is 18 V over 20 ohms datashert ohm resistor plus 10 ohm motor resistancethe current always 0. Is it a steady current? Lastly, when you measured the. So, for our understanding, tell us what you have connected to pin Your RMS current in the datasneet, I would think would lead to decreased motor life.

No wonder it is hot. For testing purposes, get a 10 ohm, watt resistor and mount datasbeet away from your circuit board until you get a feel for what is going on. Hi, Hope that you have resolved all issues, please share the info with us. Disconnect the motor and measure the motor resistance with and ohmmeter.

I purposely make it forward and reverse. Place as near as possible to the V pin. This is a very good problem to take a lot of measurements and then learn how the components involved actually work. You either drop volts across a limiting resistor or across the chip. BTW, 50 ohms also get too hot. This creates watts, which then creates heat. If I change the resistor to higher value, like ohm.
