AIC1520

AIC1520 Single High-Side Power Switch n FEATURES l l l l · 120mW (5V Input) High-Side MOSFET Switch. 500mA Continuous Load Current. 80mA Typical On-State Supply Current. Current-Limit / Short Circuit Protection. Thermal Limiting Protection under Overcurrent Condition. l n DESCRIPTION switch for The AIC1520 is an integrated high-side power self-powered and bus-powered Universal Serial Bus (USB) applications. The high-side switch is a MOSFET with 120mW RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length. 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. Guaranteed minimum output rise time limits Undervoltage Lockout Ensures that Switch is off at Start Up. Output can be Forced Higher than Input (Off-State). Slow Turn ON and Fast Turn OFF. l l n APPLICATIONS l l l l l Motherboard USB Management. USB Power Management. Hot Plug-In Power Supplies. Battery-Charger Circuit. Power Distribution Switch. inrush current during hot plug-in, minimizing EMI and preventing the voltage at upstream port from dropping excessively. n TYPICAL APPLICATION CIRCUIT Ferrite Bead AIC1520 VCC 5.0V + 33m F IN OUT 0.1mF + GND VBUS *33mF 0.01mF D+ DGND * 33mF, 16V Tantalum, or DATA 100mF, 10V Electrolytic Bold line indicate high-current traces USB High-Side Power Switch Analog Integrations Corporation DS-1520-00 Jul...
