TPS3619: Differences btw TPS3619-33 and TPS3620-33

Is the battery freshness seal the only difference btw the TPS3619-33 and the TPS3620-33?

They look p2p and functionally equivalent, otherwise, but a parametric table comparison says the TPS3620 monitors two rails vs one rail for the TPS3619?

Please let me know.

Thanks, John Garrett TI-AFA
