DRV8844: Package Dimensions & Footprint Verification

Michael Seaman

Part Number: DRV8844

Tool/software:

I have a few questions about the PWP package footprint with regard to the DRV8844PWPR specifically.

The most recent datasheet revision for the DRV8844PWPR contains package drawing PWP0028V. According to the package drawing and note 5 on page 24 of the datasheet, the thermal pad on this package may or may not have features that extend beyond the normal thermal pad.

Does the DRV8844PWPR have these features?

Thank you!

Hello Michael,

This might be due to tolerances of those dimensions. I have reached out to the systems engineer who is in charge of this devices and will give you an update tomorrow.

Can you tell me what impact this will have on your end application?

Best,

Keerthi

We have strict requirements that I do not have the liberty to speak about unfortunately, but I need to know if these additional features are present on the thermal pad.

Hi Michael,

I have reached out to the packaging team for an answer, but have little success. Have escalated the issue to see if there is a way for us to find out.

Sorry for the delay on this. Let me get back to you next week on this.

Karan

Hi Michael,

I can confirm that a small portion of the tie bar you have circled in the image will indeed be exposed. Features will hence be present. Due to confidentiality reasons I am unable to share the image in here. Let me know if you have additional questions.

Regards,
Karan
