NIV3071MTW4TWG

Current Regulation/Management Overview

The NIV3071MTW4TWG is a four-channel electronic fuse (eFuse) power distribution IC manufactured by onsemi. It supports an input voltage range of 8 V to 60 V, with each channel capable of delivering up to 2.5 A. The device features a maximum on-resistance of 92 mΩ and includes a current limit setting of 500 mA. Designed for automotive applications, it complies with AEC-Q100 standards and operates within a temperature range of -40°C to +150°C. The component is housed in a WQFNW-16 package with wettable flanks.

Current Regulation/Management Feature Summary

• Four independent high-side channels with individual enable control and shared fault indication
• Integrated thermal protection with automatic retry functionality upon fault clearance
• Adjustable overcurrent limit and turn-on time control via external components
• Automotive-grade reliability compliant with AEC-Q100 and PPAP requirements

Current Regulation/Management Applications

• Automotive body control modules
• Power distribution boxes
• Automotive zone controllers
• Low-to-medium power load protection such as lighting and motors

Current Regulation/Management Procurement Notes

Verify the specific suffix MTW4TWG against official datasheets to confirm the WQFNW-16 package with wettable flanks configuration. Ensure compatibility with automotive quality standards including AEC-Q100 and PPAP requirements. Confirm that the selected variant matches the required operating temperature range and electrical specifications for the target application environment.

Current Regulation/Management Selection Notes

Select this component when designing systems requiring robust protection for multiple loads in automotive environments. The integrated eFuse design eliminates the need for external current sense resistors, simplifying PCB layout. Consider the adjustable current limit and soft-start features for managing inrush currents and protecting sensitive downstream components from short circuits and overloads.

Current Regulation/Management Part Context

This part belongs to the NIV3071 series of four-channel eFuses from onsemi. It serves as the automotive-grade counterpart to the NIS3071, offering identical pinout and functional characteristics while meeting stricter automotive qualification standards. The series is designed for high-reliability power distribution in vehicles and other demanding industrial applications.

Current Regulation/Management Replacement Considerations

The NIS3071MT4TWG is a compatible industrial-grade alternative with identical pinout and functionality but without automotive-specific qualifications.
