Hi team,
As we known, in ISO5452, there are internal Pull-down resistor in IN+ pin and internal pull-up resistor in IN- pin.
What is the resistors’ value of internal Pull-down resistor and pull-up resistor? We can’t find in the datasheet.
Do we need add external resistor between IN+ pin and IN- pin? Because there are internal Pull-down and pull-up resistors, I think it don't need add external resistor between IN+ pin and IN- pin. But why do some boards still need add it ?
Could you have any idea and suggestions? Thank for your help!
