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.
