The TPS25221 is intended for applications such as USB where heavy capacitive
loads and short circuits may be encountered. The programmable current-limit threshold maybe set
between 277 mA and 2.7 A (typical) using an external resistor. Current-limit accuracy as tight as
±10% can be achieved at the higher current-limit settings. The power-switch rise and fall times are
controlled to minimize current surges during turn on and turn off.
The TPS25221 limits output current to the programmed level when the output
load attempts to exceeds the current-limit threshold. The FAULT output
asserts low during overcurrent conditions.
