    Products Detail

    The RT9721A/B are low-voltage, single N-MOSFET high-side power switches optimized for USB applications. They feature a charge pump to drive the internal MOSFET switch with low R_DS(ON) of 80mΩ to meet USB voltage drop requirements. The devices include a fault flag output, soft-start for inrush current control, thermal shutdown, under-voltage lockout (UVLO), and reverse current blocking. They guarantee 500mA continuous load current with low quiescent current (50μA typical at switch on state). Available in SOT-23-5 package, RT9721A lacks output auto-discharge while RT9721B includes this function.

    Key Features

    • Compliant to USB Specifications, Built-In N-MOSFET, Typical R_DS(ON): 80mΩ, Low Supply Current: 50μA Typical at Switch On State, 0.1μA Typical at Switch Off State, Guaranteed 500mA Continuous Load Current, Wide Input Voltage Ranges: 2.5V to 5.5V, Open-Drain Fault Flag Output, Hot Plug-In Application (Soft-Start), 2.15V Typical Under-Voltage Lockout (UVLO), Current Limiting Protection, Thermal Shutdown Protection, Reverse Current Flow Blocking (no body diode), UL Approved −−−−− E219878, RoHS Compliant and Halogen Free
