AIC1518中文资料Dual USB High-Side Power Switch数据手册AIC规格书

描述 Description

The AIC1518 is a dual high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. Both high-side switches are MOSFET with 110m 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 for each channel. Output current is typically limited to  1.25A, and the thermal shutdown functions of the power switches independently control their channel under overcurrent condition. 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.
