TPS38-Q1: VDD and SENSEx floating

Part Number: TPS38-Q1
Other Parts Discussed in Thread: TPS37

Hello Team,

When TPS37/38-Q1 SENSE1 is connected to VBAT but VDD and SENSE2 is floating (not available ) - is there any risk to back-power from SENSE1 to VDD.? Are any series diodes needed between VDD and supply to prevent back-powering?
