AIC6178
1.0A Dual USB High-Side Power Switch
 FEATURES
 ^DESCRIPTION
 2.7V to 6.5V Input Voltage Range
 1.0A Dual Continuous Load Current
• 100mΩ High-Side P-MOSFET Switch
• 20Ω Open-Drain Over-Current Flag Output
• 80uA Quiescent Supply Current
• 150°C Thermal Shutdown Protection
• Short Circuit Current Fold-back Protection
• 2.3V Under Voltage Lockout
• Soft Start prevents large Inrush Current
• 9ms Error Flag Delay Time (AIC6178D)
• Reverse Current Blocking
• Enable Active-High or Active-Low Version
The AIC6178 integrates dual 100m high-side
power switches for self-powered and
bus-powered Universal Serial Bus (USB)
applications. It operates with inputs ranging
from 2.7V to 6.5V, making it ideal for both 3 V
and 5V systems.
The protection includes current limiting with
fold-back, short circuit and thermal shutdown
under over-current occurs. Fault current is
limited to typically 1.5A in accordance with the
USB power requirements. The AIC6178 is
ideal for any system where current limiting and
power control are desired.
 APPLICATIONS
 USB Power Management.
 Notebook PCs
 Battery-Charger Circuit.
Guaranteed minimum output rise time limits
inrush current during hot plug-in as well as
minimizing EMI and prevents the voltage at
upstream port from dropping excessively.
