SY6280AAC

The SY6280AAC is a Silergy low-loss power distribution switch in SOT-23-5, a 5.5 V, 2 A device with a programmable current limit set by an external resistor, over-temperature protection and reverse blocking, as documented in the official SY6280 application note and ordering table. It protects USB ports and downstream rails in datacards, dongles and portable equipment by limiting fault current instead of letting a short collapse the supply. Selection advice: SY6280AAC and the near-identical SY6280AAAC differ in output-discharge behaviour — match the full code letter for letter. This code was previously reported as not found only because its product page was delisted; the code itself is confirmed in Silergy's official ordering table. Parameters verified against Silergy Corp documentation.
