Note 3: All units are 100% production tested at TA = +25NC. Limits over the operating temperature range are guaranteed by
design and characterization; not production tested.
Note 4: Not production tested, user settable. See overvoltage/undervoltage lockout instructions.
Note 5: Guaranteed by design; not production tested. UVLO and OVLO are internally clamped to BG reference voltage.
Note 6: The current limit can be set below 700mA with a decreased accuracy.
Note 7: All timing is measured using 20% and 80% levels.
Note 8: The ratio between autoretry time and blanking time is fixed and equal to 30.
