TPS2H160-Q1: Output Pullup

Hi Jegan,

1)

The 20 kOhm resistor is needed for the device to be able to detect an open load event by measuring (Vs - Vout) < V(ol,off)

if that resistor is not their it will not be able to determine if there is an open load

2)

that load seems fine

Hi Jegan,

The TPS2H160 has an EVM that uses the chip, you can use that as a reference for your design:

Hi Jegan,

The EVM has most of the configuration you should need is there something your looking for?

Hi Jegan,

We don't have a recommended D and TVS as it can depend based on the inductance of your load however we do have the calculations you can do to determine the correct diode and TVS to pick in section 8.3.4 of the data sheet.

If you would like more info on how to drive inductive loads we also have a detailed application note going over it here:
