Overview
The NCP382LD05AAR2G is a dual high-side power distribution switch manufactured by onsemi. It features two independent outputs with a maximum output current of 1.5 A per channel and a fixed current limit of 1 A. The device has a maximum on-resistance of 140 mΩ and operates within a supply voltage range of 2.5 V to 5.5 V. Key timing parameters include a maximum turn-on time of 3 ms and a maximum idle time of 3 ms. It supports overcurrent protection and is designed for power distribution applications.
Feature Summary
- Dual-channel high-side power switching capability
- Integrated fixed current limiting for overcurrent protection
- Low on-resistance for efficient power delivery
Applications
- Power distribution in embedded systems
- Peripheral power management in industrial equipment
- Load switching in automotive electronics
Procurement Notes
Verify the exact suffix 'AAR2G' against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Confirm end-of-life status as indicated by distributor records, which may affect long-term availability. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component when dual isolated high-side switching with fixed current limits is required. Compare on-resistance and current ratings against alternative channels if higher load capacity is needed. Verify that the 2.5 V to 5.5 V control voltage range matches the system logic levels. Consider thermal dissipation capabilities given the 140 mΩ resistance at full load.
Part Context
This part belongs to the NCP382 series of fixed current-limiting power-distribution switches. It is functionally similar to the NCP382LD10AAR2G but differs in specific electrical characteristics such as current limit settings. The series is designed for robust power management in compact packages.
Replacement Considerations
The NCP382LD10AAR2G is a related dual-channel variant within the same family. Verify pinout compatibility and ensure that differences in current limit thresholds do not impact circuit protection requirements before substitution.
