VNQ7140AJ-E

Power Distribution Switches, Load Drivers Overview

The VNQ7140AJ-E is a quad channel high-side driver manufactured using ST proprietary VIPower technology and housed in a PowerSSO-16 package. Designed for automotive applications, it drives 12V grounded loads through a 3V and 5V CMOS-compatible interface. The device integrates advanced protective functions including load current limitation, overload active management by power limitation, and overtemperature shutdown with configurable latch-off. A dedicated multifunction multiplexed analog output pin delivers sophisticated diagnostic functions, including high precision proportional load current sense, supply voltage feedback, and chip temperature sense.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix (e.g., -E) against the manufacturer's latest datasheet to confirm package type and compliance status. Ensure the source document explicitly lists the part as active or production data. Cross-reference the PowerSSO-16 package dimensions with your PCB footprint requirements before finalizing procurement decisions.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a quad-channel solution with integrated analog diagnostics is required for 12V automotive loads. The VIPower M0-7 technology offers robust protection features suitable for harsh environments. Consider the multiplexed analog output if space-constrained designs need to monitor current, voltage, and temperature through a single pin interface.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the VNQ7140 series of high-side drivers from STMicroelectronics. It utilizes VIPower technology, which integrates power MOSFETs and control logic on a single silicon die. The device is designed to replace discrete solutions, simplifying design while providing enhanced reliability and diagnostic capabilities for automotive electronic control units.

Power Distribution Switches, Load Drivers Replacement Considerations

Check for VNQ7140AJ without the -E suffix for potential package or qualification differences. Verify compatibility with existing thermal management strategies, as the PowerSSO-16 package requires adequate copper trace area for heat dissipation during operation.
