Notes
25. In the extended operating range the performance may be degraded
26. Transient loading for load steps of ILmax/2
27. In this mode, current limit protection is disabled for SW1 - SW4 by setting SWILIMB = 1. Therefore, the load on SW1-4 should not exceed
the conditions specified in the table above. Application needs to provide current limit protection circuitry either in battery or as pre-
regulated supply to BP.
