The 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 110m RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length. Multi-purpose indicates open-drain fault flag output thermal
500mA Continuous Load Current per Channel. 110 µA 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.
shutdown, or undervoltage lockout for each channel. Output current is typically limited to 1A, well below the 5A safety requirement, and the thermal controls condition. Guaranteed minimum output rise time limits inrush current during hot plug-in, minimizing EMI and preventing the voltage at upstream port from dropping excessively. shutdown each function under independently overcurrent channel
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.
USB Power Management. Hot Plug-In Power Supplies. Battery-Charger Circuit.
