'[EE]: Bi-directional solenoid driver chip wanted'

Hi,

I'm looking for a multiple bi-directional (polarity) solenoid driver
chip.  I need to drive up to 12V and ~1A and I have 5 solenoids to drive,
but only need to pulse one solenoid at a time.

Rohm seem to have designed some suitable 2 channel motor drive chips such
as the BA6238AN, but no-one seems to have any stock.  Can anyone suggest a
suitable device?

John

John, are you actually drawing 1 amp per solenoid ?

Max solenoid current could be around 1A, but can't be exact about this.  I
only need to pulse a single solenoid at a time for around 100ms, every few
seconds.

John, take a look at the ULN2003 Darlington array.  It will sink 500ma
continuously.  Check the data sheet - it might take 1 amp for very short
periods.  It has a built in flyback diode to protect the chip.

Thanks, that's fine for a unipolar drive, but I need bi-polar, such as
offered by a bridge driver.  I'm just fishing for suggestions of a device
that is actually available, not vapourware like the Rohm stuff.

John,

How about the good old L293D dual bridge driver?

Maybe try the old M54543. Drives one motor or two solenoids, 3A. Try to
get it as a spare part. It is used in some VCRs I think.

Then take a look at the ST web site. They have a number of driver chips
designed to bipolar drive stepper motors and brushless DC motors. Chips like
the L293 (IIRC) and L6203 may be the sort of devices you want, but they do
have a range of chips (and application notes) available.
