RT9728AHGQW

The RT9728A is a cost effective, low voltage, single
P-MOSFET high-side power switch IC for USB application
with a programmable current limit feature. Low switch-on
resistance (typ.120mΩ) and low supply current (typ.
120μA) are realized in this IC. The RT9728A offers a
programmable current limit threshold between 75mA and
1.3A (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 from happening due to high inrush current.
The RT9728A is an ideal solution for USB power supply
and can support flexible applications since it is functional
for various current limit requirements. It is available in
SOT-23-6 and WDFN-6L 2×2 packages.
