AIC1526 Dual USB High-Side Power Switch FEATURES • 110mΩ (5V Input) High-Side MOSFET Switch. 500mA Continuous Load Current per Channel. 110µA Typical On-State Supply Current. 1µA Typical Off-State Supply Current. Current-Limit / Short Circuit Protection. Thermal Shutdown Protection under Overcurrent Condition. Undervoltage Lockout Ensures that Switch is off at Start Up. Output can be Forced Higher than Input (OffState). Open-Drain Fault Flag. Slow Turn ON and Fast Turn OFF. Enable Active-High or Active-Low. DESCRIPTION The AIC1526 is a dual high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. One high-side switch is a MOSFET with 110mΩ RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length. Multi-purpose [ ... ]
