Note 1: All devices are 100% tested at T
A
= +25°C and +85°C. All temperature limits at -40°C are guaranteed by design.

.
Note 4: Tested at +25°C & +85°C. Guaranteed by design at -40°C.
Note 5: The circuit-breaker programming current increases linearly from V
CC
= 2.25V to 5V. See the Circuit-Breaker Current vs.
Supply Voltage graph in the
Typical Operating Characteristics .
Note 6: See the
Startup Mode section for more information.
Note 7: V
