Overview
AIC1523 500mA Power Distribution Switch n FEATURES • 120mΩ (5V Input) High-Side MOSFET Switch.
l 500mA Continuous Load Current.
l 80µA Typical On-State Supply Current.
l 1µA Typical Off-State Supply Current.
l Current-Limit / Short Circuit Protection.
l Thermal Limiting Protection under Overcurrent Condition.
l Output can be Forced Higher than Input (Off-State).
l Active-High or Active-Low Enable.
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.
