The NCV47722PAAJR2G is a single-channel high-side power switch IC from onsemi, designed for robust load distribution in automotive and industrial environments. It supports a supply voltage range of 4.4 V to 40 V and delivers a continuous output current of 250 mA. The device features an adjustable current limit ranging from 10 mA to 350 mA, enabling precise protection against short circuits and overloads. With a maximum turn-on time of 25 µs, it ensures rapid response for dynamic loads. Operating within a temperature range of -40°C to +150°C, the component meets AEC-Q100 qualification standards for automotive reliability. Packaged in a 14-TSSOP with an exposed pad for enhanced thermal dissipation, it integrates status flagging and comprehensive fault protection mechanisms.

Feature Summary

• Adjustable current limiting capability allows customization of overload protection thresholds between 10 mA and 350 mA.
• Integrated thermal shutdown and status flagging provide real-time monitoring and safeguarding against overheating conditions.
• High-side switching architecture simplifies control logic by utilizing non-inverted input interfaces for direct drive compatibility.

Applications

• Automotive body electronics load distribution
• Industrial motor control circuit protection
• General purpose high-side switching in harsh environments

Procurement Notes

Verify that the specific suffix PAAJR2G matches the required tape-and-reel packaging configuration for automated assembly processes. Confirm that the AEC-Q100 automotive grade certification aligns with your system's reliability requirements. Ensure the 14-TSSOP-EP footprint matches your PCB layout constraints, particularly regarding the exposed pad thermal connection. Cross-reference the adjustable current limit settings with your application's maximum load specifications to prevent premature triggering or insufficient protection.

Selection Notes

Select this component when a single-channel high-side switch with adjustable current limiting is required for loads up to 250 mA. The wide operating voltage range of 4.4 V to 40 V makes it suitable for both 12 V and 24 V automotive systems. Consider the 14-TSSOP package if space efficiency and thermal performance via the exposed pad are priorities. The non-inverted input interface simplifies driver selection, while the integrated fault protection reduces external component count compared to discrete solutions.

Part Context

The NCV47722 belongs to onsemi's family of intelligent high-side power switches designed for demanding applications. It complements other devices like the dual-channel NCV47823, offering a single-channel alternative for cost-sensitive or space-constrained designs. Part of the broader NCV series, it adheres to strict automotive quality standards, ensuring consistency with other components in advanced driver assistance and power management systems.

Replacement Considerations

Direct functional substitutes include the NCV47823PAAJR2G for dual-channel requirements. Verify pinout compatibility and thermal characteristics when replacing with generic high-side switches. Ensure any alternative maintains the 4.4 V to 40 V operating range and 250 mA current capacity.
