TPS2041B: /OC pin behavior

user6004480

Part Number: TPS2041B

Tool/software:

Hi expert,

We have question about the conditions under which the /OC pin of the TPS2041BDBVR transitions to low.
As shown in the capture below, is it correct to understand that when an overcurrent of typical 1.55A is detected, the /OC pin transitions to low?

We evaluated and captured waveforms.
When the current at the OUT pin was increased to about 1.522A with the /EN pin enabled, the /OC pin transitioned to Low.

Hi user6004480,

TPS20x1B and TPS20x2B devices in the D, DGN, and DBV packages do not have overcurrent trip thresholds. Current is limited to IOS under different test condition. Check Section 8.3.7 for more details.

Please check if your TPS2041B is D or DGN or DBV. If not these three, we can continue the discussion if needed.

BR,
