The dark current of the low-power wake-up button of the vehicle TP exceeds the standard [Copy link]

Dear experts, I am working on car TP. Recently, a project has a screen-off wake-up function. A low-power button is specially designed to achieve this function. It is required that the current flowing through this button line cannot exceed 0.5mA in the low-power state. However, the current detection actually exceeds 0.5mA. The customer requires a review. Are there any protective measures to reduce this current? Currently, POWERKEY does not add any protection circuit.

This needs to be analyzed based on the specific circuit.
