1 / 15 page RT9715 1 DS9715-03 April 2011 www.richtek.com Ordering Information Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. 90m Ω Ω Ω Ω Ω, 2A/1.5A/1.1A/0.7A High-Side Power Switches with Flag General Description The RT9715 is a cost-effective, low-voltage, single N-MOSFET high-side Power Switch IC for USB application. Low switch-on resistance (typ. 90m Ω) and low supply current (typ. 50uA) are realized in this IC. The RT9715 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 RT9715 is an ideal solution for USB power supply and can support flexible applications since it is available in various packages such as SOT-23-5, SOP-8, MSOP-8 and WDFN-8L 3x3. Applications USB Peripherals Notebook PCs Marking Information For marking information, contact our sales representative directly or through a Richtek distributor located in your area.
