Hi Masazumi-san,

I will need to ask the factory for the data.

Assuming the worse case, using the figures in the datasheet, we would take the max Vcc turn on, 16.6V and assume that the min value of the UVLO hysteresis is 5.8V, which gives 10.8V for the max turn off threshold.

In reality I think the value will be less that 10.8V but I need to check.

Regards

Peter
