DRV5013: Need help creating a BOM

Michael Luffman
Prodigy 20 points
Part Number: DRV5013

Hey all,

I'm currently taking an undergrad design course that requires me select a TI sensor product and create a report on it. Part of that requires a bill of materials for the DRV5013. I've contacted TI support and was told this was proprietary information, which makes sense. The thing is, I'm not trying to run TI out of business, I'm just trying to get an A on this report.

The type of thing I would be looking for is a gate/transistor count, capacitor count, inductor count, etc... like

1x uF capacitor

1x 5mH inductor

2x 100 ohm resistor

Any advice on how I would go about creating this would be greatly appreciated. Thanks!

    Hi Michael,

    I can tell you this IC has thousands of transistors, but not exact counts and component values.  Outside the magnetic sensing Hall effect element, the rest of the IC isn't too different from other TI ICs on this process node.

    One interesting thing though is that you can go to this website and pull up the full material content of each device: http://www.ti.com/quality/docs/materialcontentsearch.tsp

    Best regards,

    Thank you Mastermind, so trying to build a BOM is kinda pointless? Maybe not a transistor count. More like resistor, op amp, inductor, capacitor, etc... count.

    I'm sort of in over my head on this project. I understand the Hall effect and the idea behind the sensor, but I've never seen a regulated supply, bias, or almost any black box in the schematic for the DVR5013.

    What I'm trying to avoid is putting down

    1x Regulated supply
    1x Bias
    1x Offset voltage

    etc.... Since we are supposed to have a price next to each component.

    Anyways, thanks for the link, thats pretty neat if nothing else.

    Cost is a function of silicon area, number of masks, and process node. Even if you found out an IC had 200 50pF capacitors, you'd also need to know each's die area and the cost per area to get to cost.
