TPS3896: Question about TPS3896A timing

Jade,

For TPS389xA versions, both SENSE and ENABLE have a capacitor-adjustable delay. The output asserts after this capacitor-adjustable delay when both SENSE and ENABLE inputs are good.

TPS3896A: Active low EN, Active low, push-pull OUTPUT

Driving /ENABLE high makes /SENSE_OUT go high, regardless of Vsense. With Vsense already above Vit+, driving /ENABLE low will make /SENSE_OUT go low after the capacitor-adjustable delay time.

So if for this device, if /ENABLE goes high, /SENSE_OUT will go high after td(OFF) = 200ns.

See Figure 3 for TPS3896A (don't use Figure 1 since this is for the wrong device)

I hope this answers your question! Let me know if you have any more questions. Thank you!
