RT9741AGV

Overview

The RT9741AGV is a cost-effective, low-voltage, single N-channel MOSFET high-side power switch IC designed for USB applications. It integrates an N-channel MOSFET with control and protection circuitry in a compact SOT-23-3 package. The device provides simple on/off control of the load current while offering comprehensive protection features including over-current, over-temperature, and reverse voltage protection.

Feature Summary

• Integrates a single N-channel MOSFET with control logic for high-side switching
• Provides built-in over-current, over-temperature, and reverse voltage protection
• Designed specifically for low-voltage USB power distribution applications

Applications

• USB port power switching
• Portable electronic device power management
• High-side load switching in consumer electronics

Procurement Notes

Verify the exact suffix 'AGV' corresponds to the SOT-23-3 package and specific electrical characteristics as defined in the official Richtek datasheet. Confirm manufacturer authenticity through authorized distributors to ensure component integrity and compliance with specified performance standards.

Selection Notes

Select this component when a compact, single-channel high-side switch is required for low-voltage USB loads. Consider the SOT-23-3 package constraints and the integrated protection features suitable for portable devices requiring simple control interfaces without external components.

Part Context

The RT9741 series belongs to Richtek's portfolio of power management ICs focused on USB and portable applications. This specific model represents a simplified solution for basic power distribution needs, distinguishing itself from multi-channel or more complex driver variants within the broader product line.

Replacement Considerations

Consult official substitution guides for equivalent single-channel high-side switches. Verify pin compatibility and electrical ratings before replacing with other manufacturers' parts.
