VNL5050S5TR-E

Power Distribution Switches, Load Drivers Overview

The VNL5050S5TR-E is a low-side gate driver from the OMNIFET III family, manufactured by STMicroelectronics using VIPower technology. It features a single output capable of handling 19 A drain current with a typical on-resistance of 50 mΩ. The device operates within a supply voltage range of 3.5 V to 5.5 V and supports load voltages up to 36 V. It includes an open-drain status output for fault indication. Key protection mechanisms include thermal shutdown with automatic restart, fixed current limiting, overtemperature detection, and overvoltage clamping. The component is housed in an 8-SOIC package and meets AEC-Q100 automotive qualification standards.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'TR-E' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the 8-SOIC footprint matches your PCB design guidelines. Ensure compatibility with the 3.5 V to 5.5 V logic input levels. Check for RoHS compliance status if required by your manufacturing regulations. Validate that the AEC-Q100 qualification meets your automotive project specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a robust low-side driver with integrated protection is needed for automotive loads. The 19 A output current suits high-power actuators like valves or lamps. The open-drain status output allows for diagnostic feedback without additional components. Consider the 8-SOIC package size for space-constrained designs. Ensure the operating temperature range of -40°C to +125°C aligns with your environmental requirements.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the VNL5050S5-E series within the OMNIFET III family. It utilizes STMicroelectronics' VIPower technology for monolithic integration. The device is designed specifically for automotive applications requiring high reliability and built-in diagnostics. It serves as a replacement for older discrete solutions by combining the driver, switch, and protection circuitry into a single chip.

Power Distribution Switches, Load Drivers Replacement Considerations

The VNL5050N3-E is a pin-compatible alternative in the same family but uses a SOT-223 package instead of SOIC-8. Verify package dimensions and thermal characteristics before substitution. No other direct substitutes are confirmed in the provided documentation.
