NCP370MUAITXG

Overview

The NCP370MUAITXG is a high-side power switch with an integrated driver, manufactured by onsemi. It features an N-channel output capable of delivering up to 1.3A of continuous current. The device operates within a load voltage range of -28V to +28V and utilizes a 12-LLGA (3x3) surface-mount package. Key electrical characteristics include a typical on-resistance of 130 milliohms and a non-inverting input interface. The component supports a 1:1 input-to-output ratio and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates overvoltage protection, fixed current limiting, overtemperature shutdown, and undervoltage lockout for comprehensive circuit safeguarding.
• Features controlled slew rate functionality to minimize inrush currents and electromagnetic interference during switching events.
• Includes a status flag output to provide real-time feedback on the operational state and fault conditions of the power switch.

Applications

• High-side load switching in industrial automation control systems
• Power distribution management in automotive electronic modules
• Protection circuits for peripheral devices in embedded computing platforms

Procurement Notes

This component has been officially discontinued by the manufacturer as indicated by Product Change Notification documents. Availability is restricted to surplus stock held by third-party distributors such as Rochester Electronics. Verify authenticity and lot traceability carefully when sourcing from secondary markets, as original manufacturing supply chains are no longer active for this specific part number.

Selection Notes

Engineers should evaluate alternative components due to the discontinuation status of the NCP370MUAITXG. When selecting a replacement, prioritize devices that match the 12-LLGA package dimensions and the 1.3A current handling capability. Ensure the substitute offers comparable protection features, including overvoltage and thermal shutdown, while maintaining compatibility with the required -28V to +28V load voltage range and single-ended control interface.

Part Context

The NCP370 belongs to the NCP370 series of high-side power switches designed for robust load management. This series emphasizes reliability through integrated fault protection mechanisms suitable for demanding environments. The MUAITXG suffix denotes the specific tape-and-reel packaging configuration and temperature grade, aligning with standard surface-mount assembly processes for high-volume production applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct pin-compatible replacements must be identified through independent cross-reference tools or manufacturer recommendations. Verify that any potential substitute matches the 12-LLGA footprint and electrical specifications before integration.
