Note 1: All currents into the device are positive; all currents out of the device are negative. All voltages are referred to device
ground unless otherwise noted.
Note 2: ∆V and ∆V are the changes in V and V , respectively, when the DI input changes state.

Note 4: Maximum current level applies to peak current just prior to foldback-current limiting; minimum current level applies during
current limiting.
