200mA/500mA Selectable
Current-Limit Switches
________________________________________________________________________________________ 3
Note 1: All parts are 100% tested at +25°C. Electrical limits across the full temperature range are guaranteed by design and corre-
lation.
Note 2: Latch-off current does not include the current flowing into FLAG.
Note 3: TDFN parts are guaranteed by design.
Note 4: The on-time is defined as the time taken for the current through the switch to go from 0mA to full load. The off-time is defined
as the time taken for the current through the switch to go from full load to 0mA.
Note 5: Retry time is typically 15 times the blanking time (typ).
ELECTRICAL CHARACTERISTICS (continued)
(VIN = +2.0V to +4.5V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VIN = +3.3V, TA = +25°C.) (Note 1)
