RT9715CA
90mΩ, 1.5A High-Side Power Switches with Flag
General Description
The RT9715CA is a cost-effective, low-voltage, single
N-MOSFET high-side Power Switch IC for USB application.
Low switch-on resistance (typ. 90mΩ) and low supply
current (typ. 50μA) are realized in this IC.
The RT9715CA 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
RT9715CA is an ideal solution for USB power supply and
can support in package SOT-23-5.
