Hi Team,

I am promoting TPS54200/TPS54201 and noticed that there are 2 different modes, but I did not find description.

Could you help to describe or share some materials of these 2 modes?

Thanks,

Rebecca

Hello Rebecca

for shut down and latch mode, once the fault is triggered, the device enters shutdown mode and FET keeps off. The only way to activate the device is to re- power input voltage, otherwise it stays in shut down.

for auto-retry mode, once the fault is triggered, device enters shutdown mode, but if current or voltage comes back to normal value, the device can work again and there is no need to re-power input voltage.
