The TJ2205 series support the following USB requirements. Each of the two channels supplies up to 500mA as required by USB downstream devices. Each switch’s low on-resistance meets USB voltage drop requirements. Fault current is limited to typically 1.2A. Flag output indicates fault conditions to the local USB controller. Soft-start prevents the transient voltage drop on the upstream port that can occur when the switch is enabled in bus-powered applications. Under voltage lockout (UVLO) feature disables the output switches until a valid input voltage. Also the TJ2205 include thermal shutdown to prevent switch failure from high-current loads.
