initiated
Note 3:
All devices are 100% tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 4:
Startup period is the time during which the slow comparator is ignored and the fast comparator regulates the sense current. It is measured from the time ON is brought high.
Note 5:
Inferred from test with CTON = 10nF (MAX4273) and CTIM = 1nF.
Note 6:
The current available at GATE is a function of VGATE (see Typical Operating Characteristics).
Note 7:
Guaranteed by design.
