SLG59M1746C

Overview

The SLG59M1746C is a high-side integrated power switch featuring an N-channel MOSFET with a maximum continuous output current of 1 A. It exhibits a typical on-resistance of 17.6 mΩ and a maximum rating of 22 mΩ. The device operates within a supply voltage range of 250 mV to 1.5 V or 2.7 V to 3.6 V, supporting low-voltage control interfaces. It functions reliably across an operating temperature range from -40°C to +85°C and is housed in a compact 0.64 mm² WLCSP package.

Feature Summary

• Integrates a high-side N-channel power switch for efficient load management
• Features ultra-low on-resistance to minimize conduction losses
• Supports low-voltage logic control inputs for flexible interface compatibility
• Utilizes a miniature wafer-level chip-scale package for space-constrained designs

Applications

• Portable consumer electronics requiring compact power distribution
• Battery-powered devices needing efficient load switching
• Embedded systems with limited board real estate
• Low-voltage peripheral power control circuits

Procurement Notes

Verify the specific manufacturer lot code and date code upon receipt to ensure component authenticity and traceability. Confirm that the received packaging matches the specified WLCSP format and check for any physical damage to the solder balls. Ensure compliance with RoHS directives as indicated in official documentation before integration into final assemblies.

Selection Notes

Select this component when a single-channel high-side switch with low on-resistance is required for currents up to 1 A. It is suitable for applications where the control voltage may be lower than standard logic levels, given its support for voltages down to 250 mV. Consider the thermal performance within the small WLCSP footprint during PCB layout planning.

Part Context

This part belongs to the Renesas GreenFET series of integrated power switches, designed for high efficiency and miniaturization. The SLG59M1746C specifically targets applications requiring N-channel performance in a tiny form factor, distinguishing it from P-channel alternatives in the same family by offering lower on-resistance characteristics.

Replacement Considerations

Consult official Renesas documentation for direct pin-to-pin replacements. Verify that alternative components match the 1 A current rating, 22 mΩ maximum resistance, and compatible control voltage ranges.
