n DESCRIPTION
The AIC1523 is an integrated high-side power
switches for input power selection applications
that using in portable products or PCI interface
peripheral cards. The high-side switch is a
MOSFET with 120mΩ RDS(ON), low voltage drop
and low power consumption meet power saving
requirements . The switch ON/OFF is controlled
by CTL pin.
Output current is typically limited to 1.0A, well
below the 5A safety requirement, and thermal
shutdown function shuts the switch off to prevent
damage under overcurrent conditions.
Design easily and layout flexibility for getting
stable voltage in power transfer transition for power
selection application. Guaranteed minimum
output rise time limits inrush current during hot
plug-in, minimizing EMI and preventing the voltage
at upstream port from dropping excessively.
