TPS2H000-Q1: Current Limit Feature without UVLO functionality

Part Number: TPS2H000-Q1

Hi team,

Glad to discuss with You!!!

We have chosen the part "TPS2H000-Q1"  in our design. The requirements are mentioned below,

Design Requirement:

1) An Analog signal swings between 0V to 32V will be generated from our board as output and it will be provided to an external analog system as input.

2) This Analog output has the nominal current support of 100mA. So we have to limit the current to 150mA. We planned to use TPS2H000-Q1 for current limiting.

Limitation in using TPS2H000-Q1:

1) In our design, the analog output has the ability to provide 0V to 32V. But in this IC, due to the UVLO feature, We can't provide the output below ~4V. When it is below the UVLO threshold(~4V), the IC will not provide the output.

So is there any way to neglect the UVLO feature in this IC.

Thanks,

Ahamed Faize
