SLVS841F – NOVEMBER 2008 – REVISED AUGUST 2016 TPS255xx Precision Adjustable Current-Limited Power-Distribution Switches
1 Features 3 Description The TPS255x and TPS255x-1 power-distribution
switches are intended for applications where
precision current limiting is required or heavy
capacitive loads and short circuits are encountered
and provide up to 1.5 A of continuous load current.
These devices offer a programmable current-limit
threshold between 75 mA and 1.7 A (typical) through
an external resistor. Current-limit accuracy as tight as
В±6% can be achieved at the higher current-limit
settings. The power-switch rise and fall times are
controlled to minimize current surges during turnon
and turnoff. 1 Up to 1.5-A Maximum Load Current
В±6% Current-Limit Accuracy at 1.7 A (Typical)
Meets USB Current-Limiting Requirements
Backwards Compatible With TPS2550 and …
