(1) Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account
separately.
(2) TPS2223A, TPS2224A, TPS2226A: two switches on. TPS2220A: one switch on.
(3) Specified by design; not tested in production.
(4) From application of short to 110% of final current limit.
