Part Number: DRV8846

Hi, Team

Do we have accuracy data of accuracy of pull up & pull down resistors on tri-level input pins?

Thank you.

Hi Alvin,

What is the concern about the accuracy of the resistors?

The pullup and pulldown resistors are designed to track each other, creating a typical voltage of 1.1V when floating.

Hi, Rick

Customer concerns when they offer voltage from external resource, the integrated resistors and input resistor will divide the exact voltage on the pin.
