Hi team,

Does each channel of TPS274160 have their own short-circuit protection? Is protection influenced by SEH or SEL? Thanks.

Yuting,

Each separate channel of the TPS274160 has its own FET and therefore its own thermal/short-circuit protection. If one channel is shutoff due to thermal shutdown or short circuit, the others will remain on. The SEH/SEL bits are there to control which signal is reported through the SNS pin.
