relay driver ic

Are there any ICs for driving relays? (Especially multiple relays)

You can use ULN2003 or ULN2803
:wink:

uln2003 relay driver

IPS511 (high side) or IPS021 (low side) for larger relays

There are a lot...
Try searching in www.ti.com (Texas Instruments site). They have free samples.

relay driver circuits

UDN2580 is a good choice. Eight channel, 120mA source drivers.

Allegro has also 32 channel driver ICs with serial port!!! You
can control 32 relays by using just 4-5 TTL signals from your
microprocessors. Check UDN5833 or UDN5832 but I don't
think you can find these chips on K.köy. Try Farnell :wink:

relay coil driver ic

Hi
ULNs are best they are for relays having built in diode for reverse voltage protection. but there is limitation in the VCC voltage. if used with higher VCC voltages then it will heat up. so check for the proper IC

Added after 1 minutes:

From VCC i mean the power you will connect to relay. for smaller currents some times they work with no problems.

It depends on the relays too. I've been driving 8 small relays directly with I2C I/O expander PCA9555.

12 relay driver circuits

Hello,

I need to drive 32 NEC EA2 relays on my pcb but I want to use minimum number of driver ICs.
I was thinking about driving 4 relays from 1 output of ULN 2803 but from the datasheet I couldnt find out whether its possible or not..Besides I dont have any samples so I cant make any experiments.
Do you have suggestions for such a driver IC? Only requirement is to operate between -40 C to 85 C.

I need a response as soon as possible.
Thank you.

Re: 12 relay driver circuits

If you have a microcontroller or some kind of digital interface available, you can use TPL9202 made by TI. It can drive 8 relays with some fault protection as well (brown out condition)

Hello

you might look at the iC-JX which has 16 I/O port which can drive relays and the output port volatge can go to industrial 24V. Here you find the datasheet: https://www.ichaus.biz/product/iC-JX and applications:https://www.ichaus.biz/appnote_industrial.

Enjoy your design work!
