FP6861J中文资料Adjustable Current-Limit Single-Channel Power Distribution Switch数据手册Fitipower规格书

描述 Description

FP6861J is a cost-effective, low voltage, adjustable current limit, single N-Channel MOSFET high-side power switch, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

FP6861J is equipped with a charge pump circuitry to drive the internal MOSFET switch. The switch's low RDS(ON) meets USB voltage drop requirement, and a flag output is available to indicate fault conditions to the local USB controller. FP6861J also provides adjustable current limit threshold between 0.125~3.76A through an external resistor.

Additional features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, and under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present. Besides, fault current is limited to specific current for FP6861J in single port in accordance with the USB power requirements. FP6861J will prevent reverse current with reverse voltage protection.

FP6861J is available in SOT-23-6, TSOT-23-6, and TDFN-6 (2mm×2mm) packages with smallest components.
