'[pic]: Driving DC Motor'
I have been using CI SG3524 Texas to control a DC motor 1/8HP and 24VCC.
I am looking for new alternatives of circuits integrated to drive

Something like an LM18200 from National Semiconductor? They also have other
nice half bridge driver chips if you need beefy external FETS.
Also Intersil have some nice chips. Look at the HIP408x family. Again these
will need external FETS, where the LM18200 will drive 3 amps.
All these solutions will produce PWM which will need to be at a suitable
frequency for the motor, and may require some LC filtering, depending on
your end use.

What are you using now ? Do you want bi-directional drive ? It
looks like the SG3524 has linked alternating outputs so I presume
it doesn't do bi-directional drive. As you've posted this under the
[PIC] tag, why not a PIC and an external bipolar/FET or H-bridge
eg add PWM to this
Thanks Jinx to replay,
I have been using 1 to 200RPM.
I got this using a converter freq/Vcc (LM2917) linked with the
SG3524 plus a FET to driving the motor.
I would like a new idea get the same.
I tried do this using PIC with PWM and a FET, but the result was not good.
I tried several ways, but I didn't get a 1 RPM yet.
1 RPM?? You mean with a gear or the shaft itself of the motor has to be
rotated at 1rpm? Is that possible at all?
