The high-side switch of USB power switch is MOSFET with 150m Ω RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length. Multi-purpose open-drain fault flag output indicates over-current limiting, thermal shutdown, or undervoltage lockout. The output current of USB power switch is typical limited to 0.62A / 1.25A (control by select pin). 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. Analog Integrations Corpo...
