PCA9535: Power-On sequence

Part Number: PCA9535

Hello,

I have a question regarding the Power On sequence

How I supposed to power his device?

From the datasheet in this section:8.2.1 Power-On Reset it states that the power is applied directly to Vcc and then Vcc must be lowered to 0.2V and back to operation voltage.

Is this action is necessary for the normal operating conditions, as I understood this action needed in order to reset device?

I am not sure how to implement this, as there are other devices connected to Vcc rail and I can't just pull it low for this specific device

Best regards,

Timur
