TPS25221 Datasheet - Texas Instruments

TPS25221 2-A Continuous Current-Limited Switch

The TPS25221 is intended for applications where heavy capacitive loads and short circuits may be encountered. The programmable current-limit threshold maybe set between 275 mA and 2.7 A (typical) using an external resistor. ILIMIT accuracy as tight as ±6% can be achieved at the higher currentlimit s.
