Introduction

The TP600X is a low voltage, single P-MOSFET high-side power switch, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. The TP600X equipped with a charge pump circuitry to drive the internal MOSFET switch; the switch's low RDS(ON), 80mΩ, meets USB voltage drop requirements; and a flag output is available to indicate fault conditions to the local USB controller. Additional features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present. lower quiescent current as 20uA making this device ideal for portable battery-operated equipment. The TP600XA is available in SOT-23-5L package requiring minimum board space and smallest components.
