GENERAL DESCRIPTION
RYC8620/21/630 is a series of dual channel protected power switches designed for USB and other 3.3V to 5V
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 RYC8620/21/30 series of power switches provides channel
independent current limiting and overtemperature protection. In an overcurrent event the offending channel is
turned off allowing normal operation on the other channel. The RYC8620/21/30 features undervoltage lockout,
soft start and reverse current blocking when disabled.
RYC8620/21/30 devices are available with multiple current limits. Custom current limit levels may be available
on request.
