Tool/software:
Hello experts,
I want to know until how many amperes we can set using RIWRN resistor.
In document of TPS4811-Q1, the resistor of 52.88kohm is calculating to set 15A.
I want to set the overcurrent protection to 1.5A or 2A.
Can I set it using TPS4811-Q1 the overcurrent protection to 1.5A?
Best Regards,
Toru Kimura.
Hi Toru,
If you would like to set the I_OC = 1.5A you could achieve this using Rset = 100 ohm, and R_IWRN ~ 47.6 kohm.
You can use equations 13 and 14 in the data sheet to calculate this substituting I_OC = 1.5A.
You can also consider using the design calculator online to help determine these values. https://www.ti.com/product/TPS4811-Q1#design-tools-simulation
Thank you,
