Table 6: Enable Input ENx Characteristics (VI = 5.5V, IO = rated current, VIEN =VI, TJ = 25°C, unless

otherwise specified.) (See Note 1)

Table 7: Current Limit Characteristics (VI = 5.5V, IO = rated current, VIEN =VI, TJ = 25°C, unless other-

wise specified.) (See Note 1)

Table 8: Supply Current Characteristics (VI = 5.5V, IO = rated current, VIEN =VI, TJ = 25°C, unless oth-

erwise specified.) (See Note 1)

Table 9: Undervoltage Characteristics (VI = 5.5V, IO = rated current, VIEN =VI, TJ = 25°C, unless other-

wise specified.) (See Note 1)

Table 10: Overcurrent (OC) Characteristics (VI = 5.5V, IO = rated current, VIEN =VI, 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 sep-

arately.

Note 2: Specified by design, not production tested.

Note 3: Guaranteed by design.
