The AIC1525 is an integrated high-side power
switch for self-powered and bus-powered Universal
Serial Bus (USB) applications. The high-side
switch is a MOSFET with 70m
R
DS(ON)
, which
meets USB voltage drop requirements for
maximum transmission wire length.
Multi-purpose
indicates over-current limiting, thermal shutdown,
or undervoltage lockout. Output current is typically
limited to 0.85A below the 5A safety requirement,
and thermal shutdown function shuts the switch
off to prevent damage under overcurrent condition.
open-drain
fault
flag
output
Guaranteed minimum output rise time limits
inrush current during hot plug-in, minimizing EMI
and preventing the voltage at upstream port from
dropping excessively.
