NCV47822PAAJR2G

Overview

The NCV47822PAAJR2G is a dual high-side switch integrated circuit from onsemi, designed for power distribution applications. It features two independent channels with adjustable current limit capabilities and diagnostic status flags. The device operates within a load voltage range of 4.4V to 40V and supports an output current of 250mA per channel. It includes protection against over-temperature conditions and short circuits. The component is AEC-Q100 qualified for automotive use and is available in a 14-TSSOP package with an exposed pad.

Feature Summary

• Dual high-side switch configuration with independent channel control
• Adjustable current limit functionality for precise load management
• Integrated diagnostic features including status flags and thermal protection
• Automotive-grade reliability with AEC-Q100 qualification

Applications

• Automotive power distribution units (PDUs)
• Load switching for lighting systems
• Actuator control in vehicle electronics
• General purpose high-side switching in industrial environments

Procurement Notes

Verify the specific suffix PAAJR2G corresponds to the 14-TSSOP-EP package and reel packaging format when ordering. Confirm that the AEC-Q100 qualification meets the required automotive grade standards for the target application. Ensure design compatibility with the 4.4V to 40V operating voltage range and 250mA output current specifications before finalizing procurement.

Selection Notes

Select this component when dual-channel high-side switching with adjustable current limiting is required. It is suitable for applications needing diagnostic feedback via status flags. Consider the 14-TSSOP-EP package for thermal performance and space constraints. Verify that the input type and interface requirements align with the non-inverting open/switch control logic specified for this device.

Part Context

This part belongs to the NCV4782x series of dual high-side switches from onsemi. It shares functional similarities with the NCV47821, though the latter is an LDO regulator. The NCV47822 focuses on power distribution rather than voltage regulation. It is part of onsemi's portfolio of automotive-grade PMICs designed for robust power management in harsh environments.

Replacement Considerations

The NCV47823PAAJR2G is a related dual high-side switch but may have different electrical characteristics such as current ratings or package options. Direct pin-to-pin replacements should be verified against official cross-reference lists. No other specific substitute part numbers are confirmed in the provided documentation.
