SLG59M1551V

Overview

The SLG59M1551V is a single-channel N-channel power switch IC from the Renesas GreenFET series. It operates within a supply voltage range of 0.85 V to 1.9 V and supports a maximum continuous output current of 2 A. The device features a typical on-resistance of 15.5 mΩ, ensuring efficient power distribution with minimal loss. Designed for surface-mount applications, it utilizes a compact 4-STDFN (1x1) package. The component functions reliably across an extended temperature range from -40°C to +85°C, making it suitable for space-constrained portable electronics.

Feature Summary

• Integrates a single N-channel load switch with CMOS-compatible input logic for straightforward control interface.
• Features ultra-low on-resistance to minimize conduction losses in high-efficiency power distribution paths.
• Operates at low supply voltages starting from 0.85 V, enabling compatibility with battery-powered systems.

Applications

• Power management in portable consumer electronics
• Battery protection circuits in mobile devices
• Load switching in USB-powered peripherals

Procurement Notes

Verify the specific suffix and tape-and-reel specifications against the manufacturer's latest datasheet before ordering. Confirm that the 0.85 V minimum operating voltage aligns with your system's rail requirements. Ensure the 4-STDFN footprint matches your PCB layout guidelines. Check for any recent product change notices regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when a single-channel switch with very low on-resistance is required for low-voltage applications. The 0.85 V minimum supply voltage distinguishes it from standard 1.5 V or 2.5 V switches. Consider the 4-STDFN package size if board space is limited. Verify that the 2 A current rating meets the load requirements without exceeding thermal limits.

Part Context

This part belongs to the Renesas GreenFET family of power switches, which emphasizes high efficiency and small form factors. The SLG59 series offers various configurations including single and dual channels with different current ratings. This specific model focuses on low-voltage operation and compact packaging for modern portable devices.

Replacement Considerations

Check for direct cross-reference part numbers from Renesas or Dialog Semiconductor. Evaluate alternative single-channel N-channel switches with similar 15 mΩ resistance and 2 A current capacity. Ensure replacement parts support the 0.85 V to 1.9 V supply range and 4-STDFN package.
