STATIC ELECTRICAL CHARACTERISTICS
Table 5. Static Electrical Characteristics
Characteristics noted under conditions -40°C ≤ TA ≤ 85 °C, GND = 0 V unless otherwise noted. Typical values noted reflect
the approximate parameter means at TA = 25 °C under nominal conditions, unless otherwise noted.

Notes
13. In the extended operating range the performance may be degraded
14. Transient loading for load steps of ILmax/2
15. 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.
