Hello,

Please answer following question from customer.

ERR terminal goes high shortly when STAT0 is read by SPI in spite of VDS error is existing.

It can be understood because of error flag is cleared during short period of time.

Is Protective Action (Active Pull-down) cancelled during short period of time same with error flag(ERR terminal)?

Best Regards.

Hi Ushikubo-san,

This will depend on the condition of the IHSx and ILSx pins during the time that the ERR pin goes high. During this short time the device will try to drive the gate without the Active pullup if instructed to do so. As soon as an error is detected again, the device will re-activate the active pull-down.
