Part Number: TPS543C20

Hi,

May I know the current limit range for ILIM pin settings?

I would like to know the maximum RILIM/OCP could be used.

Thanks and Best regards,

Tiger

The adjustable range of the ILIM voltage is 0.1V to 1.2V. With the nominal Rdson of 0.58mΩ and a 16:1 divider, that corresponds to 75mV on the low-side FET or 129A, which would correspond to a 107kΩ ILIM resistor. I would not recommend programming the current limit that high. I would recommend a maximum Rilim of 75kΩ
