NCP380HSNAJAAT1G

Overview

The NCP380HSNAJAAT1G is a high-side power distribution switch from onsemi, featuring a single P-channel MOSFET output in a TSOP-6 package. It supports a load voltage range of 2.5 V to 5.5 V with a maximum on-resistance of 95 mΩ and an output current capability of 1 A. The device includes adjustable current limiting between 500 mA and 2.1 A via an external resistor. Key timing parameters include a maximum rise time of 4 ms and a maximum fall time of 3 ms. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a P-channel MOSFET with adjustable current limiting for overcurrent protection
• Features controlled slew rates to minimize current ringing during switching
• Includes internal reverse voltage detection to protect input-side components
• Provides a logic flag output indicating fault conditions such as overcurrent or overheating

Applications

• Power distribution in systems with large capacitive loads
• Applications requiring short-circuit protection capabilities
• High-side switching for peripheral power management

Procurement Notes

Verify the specific suffix JAAT1G against the manufacturer's datasheet to confirm pinout compatibility and electrical specifications. Ensure the TSOP-6 package dimensions align with your PCB footprint requirements. Confirm that the adjustable current limit setting matches your design needs using the recommended external resistor values. Check for any recent Product Change Notifications regarding manufacturing site or material changes.

Selection Notes

Select this component when a high-side switch with adjustable current limiting is required for low-voltage applications up to 5.5 V. Consider the 95 mΩ on-resistance for power dissipation calculations at the desired load current. The adjustable current limit allows customization between 500 mA and 2.1 A, offering flexibility for different load profiles compared to fixed-limit alternatives.

Part Context

This part belongs to the NCP380 series of high-side power switches designed for robust power distribution. The series integrates protection features like overcurrent limiting and thermal shutdown into a compact surface-mount package. It is intended for use in consumer electronics and industrial applications where reliable power switching and fault protection are critical.

Replacement Considerations

Check the NCP380LSNAJAAT1G for similar functionality in a TSOP-6 package. Verify if the NCP380HSNAJAAT1G variant offers identical pinouts and electrical characteristics. Consult the manufacturer's cross-reference guide for other active parts in the NCP380 family that may serve as direct replacements.
