TPD6S300A: Unused pins recommendations

Hello,

So, what should we follow? 

Please follow what is specified in the datasheet.

I just want to clarify confusion regarding the information given in this topic vs. data seeht. 

I believe the topic in the e2e thread is related to a design where the D1 and D2 pins were left floating.  While not recommended per the datasheet, this will not impact the functionality of the clamps nor the ability to provide the Rd resistors in a dead battery situation. 

It is generally good practice to ground unused pins to prevent a floating node which could raise to a potential that might cause transitions through a transistor threshold, resulting in switching and an increase in power consumption.  My suspicion is that if the D1 and D2 pins are left floating there will be no impact in performance but there may be an increase in the power consumption as specified in the datasheet.

Further remarks: 
Datasheet says for pin 16, 17: "Unused pin. Connect to Ground ". However the layout recommendation on Figure 34 doesn't have pins connected to GND. 

Thank you.  I will submit a request to update the Figure 34.

Chris
