TJ2242A

HTC Korea TJ2242A is single-channel High-Side MOSFET switch optimized for adjustable current limited power distribution requiring circuit protection. The TJ2242A  series support the following USB requirements. The TJ2242A series supply up to 2.25A 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. Auto discharge function quickly lowers the VOUT to the ground level  when the TJ2242A turns off. Also the TJ2242A include thermal shutdown to prevent switch failure from high-current loads and reverse current protection circuit to  prevent the reverse current from VOUT pin to VIN pin.
