Descriptions
The SC77101Q device is a fully-protected single channel
smart high-side switch, with an integrated 90-mΩ NMOS
power FET. Full diagnostics and high-accuracy currentsense
features enable intelligent control of the load.
External adjustable current limit improves reliability of the
whole system by limiting the inrush or overload current.
