Low side switch to drive 5V automotive relays

[lajitha]

Hello ST Team,

       We are currently desiging an ECU, which require DO that can drive external 5V automotive relays. We have identified L9338(AEC-Qualified part)  from ST for our design. Kindly confirm its selection and longevity of the part. 

Thanks & Regards

There are many low-side switches in the portfolio of STMicroelectronics, but since you have not mentioned any requirements other than the voltage of 5V and automotive, nobody can make a more detailed statement.

Regarding long-term availability, the L9338 is not guaranteed for product longevity. Future availability depends on worldwide demand. However, your preferred distributor will warn you in good time of any imminent discontinuation so that you can buy and keep sufficient stock. However, no discontinuation is currently foreseeable.

Hope that answers your question?
