BQ32002 Vback maximum reverse current

Other Parts Discussed in Thread: BQ32002

What is the maximum reverse current OUT of the Vback pin when Vcc = 3.3VDC?  We are using the BQ32002 with a lithium coin cell (CR1025) and to get through UL you have to know the "Maximum Abnormal Charge Current" that will be applied to the battery.  Are there any details on the switch over circuitry in the chip (e.g. reverse biased diodes and the like) showing that Vcc cannot be applied to Vback?

Thanks in advance for your consideration.
