SLG59M1780V

Overview

The SLG59M1780V is a high-side load switch manufactured by Renesas Electronics Corporation. It features an ultra-small footprint with an on-resistance of 4.2 mΩ and supports a continuous output current of 4 A. The device includes integrated discharge functionality for rapid load de-energization. It operates within a supply voltage range of 2.5 V to 5.5 V and is housed in a compact STDFN-4 package.

Feature Summary

• Ultra-low on-resistance for minimal power loss
• Integrated load discharge capability
• Compact surface-mount packaging

Applications

• Portable electronic devices requiring efficient power distribution
• Battery-powered systems needing low quiescent current
• General-purpose load switching in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct packaging and temperature grade. Confirm that the STDFN-4 package dimensions match your PCB layout requirements. Check for any recent product change notifications regarding labeling or material composition updates from Renesas.

Selection Notes

Select this component when minimizing board space and conduction losses are critical. The 4.2 mΩ resistance suits high-current applications. Ensure the control signal voltage aligns with the 2.5 V to 5.5 V operating range. Consider the discharge feature if fast turn-off times are required for the connected load.

Part Context

This part belongs to the GreenFET series of power switches from Renesas, designed for portable applications. It complements other single-channel load switches in the portfolio, offering a balance of low resistance and small physical size. The series targets efficiency improvements in battery-operated equipment.

Replacement Considerations

Consult the official cross-reference list for verified substitutes. Ensure any replacement matches the 4 A current rating, 4.2 mΩ resistance, and STDFN-4 package. Verify pin compatibility and electrical specifications before substitution.
