Prev Next Motor driver ICs. BTW, 50 ohms also get too hot. Again, that resistor is there to prevent a short circuit, so is it a short? The motor revolving speed can be set arbitrarily by controlling the volt. The current to the BA is too low. I would double check your wiring of the circuit and measure the ohms of the motor you are trying to drive.

I have try to eliminate the 10 ohm by connecting a wire but it burn out the B IC. The 10 ohm is connected to input of the 18 V unregulated adaptor which is datashwet to Pin 8 of the motor driver.

With Load, Speed is rpm, current 0. Why the design xatasheet the BA was in such a way?? Capacitor to prevent both output transistors being turned on at the same time Capacitor to absorb surge voltage and prevent parasitic oscillations.

I understand that when changing logic modes the driver should go through ‘open’ mode briefly.

Let us know of the outcome. Your RMS current in the motor, I would think would lead to decreased motor life. Then take the supply volts and divide that by the total ohms.

In other words, how long are you in forward mode and how long in reverse?

Reversible Motor Driver – Rohm

Register now while it’s still free! Or are you using logic to turn it on forward and reverse? BTW, right now I am betting you are at least partially turning on the reverse transistors.

Therefore recommended to place a current limiting resistor or other physical counter- measure. When motor is at rpm, that means cemf is about Even use for 0.


This will help to fill in the picture of your application. Forward and Reverse in every sec.

As a general rule, size the wattage of the resistor to twice your calculated watts. The Eng-Tips staff will check this out and take appropriate action.

The motor revolving speed can be set arbitrarily by controlling the volt- age applied to the motor. If so at high speed?

I can only touch the solder joint for 3 second. The current drive is BAB. Be sure to confirm that the back-rush voltage will not adversely affect the operation of the IC. Promoting, selling, recruiting, coursework and thesis datashfet is forbidden.

It will do this at the current you are drawing. The motor resistance is 12 ohm when I measured.

OK, let me tell all the information:
