Overview

® RT9742 70mΩ/55mΩ, 3A/2.
5A/2A/1.
5A/1A/0.
5A High-Side Power Switches with Flag General Description The RT9742 is a cost-effective, low-voltage, single N-MOSFET high-side Power Switch IC for USB application.
Low switch-on resistance and low supply current are realized in this IC.
The RT9742 integrates an over-current protection circuit, a short fold back circuit, a thermal shutdown circuit and an under-voltage lockout circuit for overall protection.
Besides, a flag output is available to indicate fault conditions to the local USB controller.
Furthermore, the chip also integrates an embedded delay function to prevent miss-operation from happening due to inrush-current.
The RT9742 is an ideal...
