DRV110: Passive Component selection as per requirement

Hello Uday,

Thanks for your question about using DRV110!

Let me provide my comments on your design by 7/7.

Meanwhile, have you tried to use the parameter selection tool to select your components based on basic requirements?

This is the best resource to ensure a functional system.

Thanks,

Kevin

Hi Kevin,

Any Update or review comments .

I am waiting for your comments.

please provide asap.

Thanks ,

Uday

Hi Uday,

Can you provide detail to which you aim to improve performance?

Thanks,

Kevin

Hi Kevin,

Only need the comments on design and the passive component i have selected id correct or not.

Hi Uday,

Based on parameters I interpreted for you (please confirm), 

I_PEAK = 4A

I_HOLD = 675mA

t_KEEP = 150ms

You can input these parameters into COMPONENT CALCULATION TOOL - DRV1xx Device Parameter Selector found on TI.com DRV110 data sheet, product information and support | TI.com. This will ensure you achieve your Design functions properly, please let me know if you have any trouble using this tool.

• What is your desired f_PWM?
• Could you explain B component in schematic, in more detail?
• Have you ran any simulations on your design?

I would appreciate if you could share more detail to your design, since this does not appear to be typical application as V_IN and OUT (Drain) typically share same voltage source:

Would be curious to learn more about your schematic, please let me know.

Thanks,
Kevin
