Hello ,

can you help to clarify the different between Isd and Ioff?

from your datasheet the test condition is same.

in our usage, we need to calculate the shutdown current consumption

Hi, Mengyao

Isd means that EN is always high, device is totally shutdown.

Ioff means that PWM/EN pin is low during the input pulse, no output, device is active.

Hello Zhiqian,

"Isd means that EN is always high, device is totally shutdown." when the EN is high, why the device will shutdown? are you sure?

Hi, Mengyao

Sorry it is a typo here.

Isd means that EN is always LOW , device is totally shutdown.
