DESCRIPTION
The UTC US203 are low voltage cost-effective high-side power switches with flag function. These devices are particularly suitable for self-powered and bus-powered USB applications. The build-in N-MOSFET’s RDS(ON) which meets the requirements of USB voltage drop is as low as 80mΩ

FEATURES
* Input Voltage Varies From 3.5V to 5.5V
* Built-in N-MOSFET
* Output Can Be Forced Higher Than Input (Off-State)
* Typical Low Supply Current:
    - Switch On: 25μA (TYP)
    - Switch Off: 0.1μA (TYP)
* Open-Drain Fault Flag Output To Indicate Fault Conditions
* Protection Circuits:
    - Soft-start( Hot plug-in application)
    - UVLO 1.7V (TYP.)
    - Current Limiting Protection
    - Thermal Shutdown Protection
* Reverse Current Flow Blocking (No Body Diode)
