AIC6186

AIC6186 0.5A Dual USB High-Side Power Switch  FEATURES  DESCRIPTION  2.7V to 6.5V Input Voltage Range  0.5A Dual Continuous Load Current +/-20% Current Limit Accuracy 85mΩ 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 (AIC6186D) Reverse Current Blocking Enable Active-High or Active-Low Version  APPLICATIONS  USB Power Management.  Notebook PCs  Battery-Charger Circuit. The AIC6186 integrates dual 85m 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 0.65A in accordance with the USB power requirements. The AIC6186 is ideal for any system where current limiting and power control are desired. 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.  TYPICAL APPLICATION CIRCUIT AIC6186 Analog Integrations Corporation Si-Soft Research Center 3A1, No.1, Li-Hsin Rd.
