50mA/100mA Current-Limit Switches
ELECTRICAL CHARACTERISTICS (continued)
(VIN = 2.3V to 5.5V, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VIN = 3.3V, TA = +25°C.) (Note 1)

Note 1: All parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.
Note 2: Latch-off current does not include the current flowing into FLAG.
Note 3: 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 4: Retry time is typically 7x the blanking time.
(VIN = 3.3V, TA = +25°C, unless otherwise noted.)
