SLG59M1721V

Overview

The SLG59M1721V is a power switch IC from the Renesas SLG59 series, designed for load switching applications. It operates within a supply voltage range of 2.5 V to 5.5 V and supports an output current of 4 A with a maximum current limit of 2 A. The device features a maximum on-resistance of 20 mΩ and a maximum turn-on time of 2.16 ms. It is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates four independent N-channel load switches in a single package
• Includes back-to-back NFET configuration for bidirectional blocking
• Supports CMOS logic input levels for direct microcontroller interfacing

Applications

• Power distribution networks in embedded systems
• Load switching for peripheral devices
• Battery-powered equipment power management

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and check for any recent product change notices (PCN) regarding manufacturing site or material updates before finalizing procurement plans.

Selection Notes

Select this component when multiple isolated high-side loads require control within a low-voltage system. Ensure the total load current does not exceed the per-channel limits and verify that the 20 mΩ on-resistance meets thermal requirements for the intended application environment.

Part Context

This part belongs to the SLG59 family of integrated power switches manufactured by Renesas Electronics. These components are engineered to replace discrete MOSFET solutions, offering reduced board space and simplified design through integrated protection and control features.

Replacement Considerations

Consult official Renesas cross-reference lists for verified substitutes. Do not assume functional compatibility with other SLG59 variants without verifying pinout and electrical parameter alignment.
