Datasheet Specifications

Part number: US1528
Manufacturer: Unisonic Technologies
File Size: 238.87 KB
Datasheet: US1528-UnisonicTechnologies.pdf
Description: CMOS IC

Features

* Open-Drain Fault Flag
* Low on-Resistance MOSFET: Typical 110mΩ(at 5.0V)
* Operating Voltage Varying From 3.0V to 5.5V
* Output can be Forced Higher than Input when Operating in Off State.
* Slow Turn-On (Soft-Start) and Fast Turn-Off
* On-State Supply Current: 100 µA (TYP)

Applications

* The UTC US1528 meets the requirements of the USB. The low on-resistance of the switch meets USB voltage drop requirements. When the output load becomes higher than the current-limit threshold, the UTC US1528 switches into constant- current mode and limits the output current at 1.4A (TYP). An open-d
