ENABLE INPUT ENx CHARACTERISTICS (VI =5.5V, IO = rated current, VIEN =0V, TJ = 25°C, unless
otherwise specified.) (See Note 1)
CURRENT LIMIT CHARACTERISTICS (VI =5.5V, IO = rated current, VIEN =0V, TJ = 25°C, unless
otherwise specified.) (See Note 1)
SUPPLY CURRENT CHARACTERISTICS (VI =5.5V, IO = rated current, VIEN =0V, TJ = 25°C, unless
otherwise specified.) (See Note 1)
UNDERVOLTAGE CHARACTERISTICS (VI =5.5V, IO = rated current, VIEN =0V, TJ = 25°C, unless
otherwise specified.) (See Note 1)
OVERCURRENT (OC) CARACTERISTICS (VI =5.5V, IO = rated current, VIEN =0V, TJ = 25°C, unless
otherwise specified.) (See Note 1)
Note 1: Pulse testing techniques maintain junction temperature close to ambient temperature: thermal effect must be takes into account
separately.
Note 2: Specified by design, not production tested.
