Descrizione

Traduzione AI

The RT9728B is a cost effective, low voltage, single P-MOSFET power switch IC for USB application with a adjustable current limit feature. Low switch-on resistance (typ. 120mΩ) and low supply current (typ. 120μA) are realized in this IC. The RT9728B can offer a adjustable current limit threshold between 75mA and 1.8A (typ.) via an external resistor. The ±10% current limit accuracy can be realized for all current limit settings. In addition, 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 mis-operation due to high inrush current. The RT9728B is an ideal solution for USB power supplies and can support flexible applications since it is suitable for various current limit requirements. It is available in the SOT-23-6 and WDFN-6L 2x2 packages.
