The TJ2100X series support the following USB requirements. The TJ2100 series supply up to 2.5A as required by USB downstream devices. Maximum continuous current can be different on the types of package and ambient temperature. Switch’s low on-resistance meets USB voltage drop requirement. Flag output indicate fault condition 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 TJ2100 include thermal shutdown to prevent s...
