Hi,
We use ISL69144IRAZ-T7A on the AMD GPU board. ISL69144IRAZ-T7A works normally at room temperature but it takes long time for PGOOD signals of ISL69144IRAZ-T7A to arrive at minus temperature.
ISL69144IRAZ-T7A and AMD GPU connected via SVI2 interface. ISL69144IRAZ-T7A has NVM. We are programming NVM with "Production Config Tool 5.4.139.0". Can NVM cause problems at minus temperature? Is there any known erreta document of ISL69144IRAZ-T7A?
