BQ2022A: PSID Timing Chart question.

Part Number: BQ2022A

Hello team,

My customer is using TI's BQ2022A in AC power adapter, right now they wants to add additional 1.6s low level onto PSID signal in order to disable the preset OCP2 from original adapter design, they are wondering if any potential risk to add additional 1.6s low level? Would it impact PSID function? if the timing chart is wrong, can you tell the correct way to add 1.6s onto the timing chart? Please see attachment.

Customer is urgent request to know the answer, could you kindly enough to get back to me by today?

Very appreciate.

Martin
