DescriptionThe TPS255x power-distribution switchis intended
for applications where precision current limitingis
requiredor heavy capacitive loads and short circuits
are encountered. These devices offer a
programmable current-limit threshold
500 mA and5A (typical) throughan external
The power-switch rise and fall times are controlled
minimize current surges during turnon and turnoff.
TPS255x devices limit the output currenttoa safe
levelby switching intoa constant-current mode when
the output load exceeds the current-limit threshold.
The FAULT logic output asserts low during
overcurrent and overtemperature conditions.
Device Information(1)(1) Forall available packages, see the orderable addendum
the endofthe data sheet.
Typical Applicationas USB Power Switch
