Note 1: Limits are 100% production tested at +25°C. Limits over temperature are guaranteed by design.
Note 2: All currents out of the device are positive; all currents into the device are negative. All voltages are referenced to device
ground unless otherwise specified.
Note 3: The ripple voltage is strongly correlated to the bus capacitance and its ESR.
Note 4: The V
BUS
current source and current gate time vary together with process and temperature such that the resulting V
BUS
pulse is guaranteed to drive a <13µF load to a voltage >2.0V, and to drive a >96µF load to a voltage <2.2V.
