... Protected Power Switch GENERAL DESCRIPTION RYC8620/21/630 is a series of dual channel protected power switches designed for USB and other 3. high-side power switched applications. Each channel can be separately enabled and has a deglitched fault flag to minimize nuisance tripping when high inrush current devices are plugged into the port. The output MOSFET typically has a low on resistance of 100m: ...

... The RYC86xx is designed to support two power ports. The current limit is 0.6A minimum and 1.25A maximum for the RYC8620, 0.7A minimum and 1.35A maximum for RYC8621 and 1.1A minimum and 2.2A maximum for the RYC8630. When the current limit is exceeded, the device will first limit the current and then, if necessary, will go into thermal shutdown when the die temperature reaches approximately 130° ...
