relay driver IC recommendation

Other Parts Discussed in Thread: DRV8251, DRV8231

Hi team,

My customer is looking for a relay driver IC with 800mA, and they have a PN (KY8023), do we have similar device to recommend?

Thanks!

Hi Jayden,

Do you have the datasheet for the KY8023? I tried searching but could not find it.

What other requirements do they need besides 800mA? What is the supply voltage and load (stepper or BDC motor)?

Regards,

Pablo Armet

Hi Jayden,

The website is in Chinese but I was able to get the most important parameters by translating. It looks like this driver is a simple H-bridge driver intended to be be used in relays for smart meter applications.

We have the DRV8251 and DRV8231 which have similar voltage range and actually higher current ratings than the KY8023. These drivers have already released to market so you can find the datasheets on ti.com. Suggest these to the customer and if it does not fit their design requirements, I can suggest other drivers.
