RT9741CGV

Overview

The RT9741CGV is a single-channel, high-side power distribution switch manufactured by Richtek USA Inc. It integrates an N-MOSFET for USB applications with a typical on-resistance of 100mΩ and a continuous output current capability of 0.7A. The device features comprehensive protection mechanisms including over-current protection, short-circuit foldback, thermal shutdown, and under-voltage lockout (UVLO). It operates within a specified input voltage range suitable for low-voltage systems.

Feature Summary

Integrates a single N-MOSFET high-side switch optimized for USB load switching applications
Includes built-in over-current protection with short-circuit foldback functionality
Features thermal shutdown and under-voltage lockout (UVLO) for system reliability

Applications

USB port power management and distribution
Peripheral device power control in consumer electronics
HMI and display project power switching

Procurement Notes

Verify component status as the RT9741CGV is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing design requirements before procurement, considering potential lead times for end-of-life components.

Selection Notes

Select this component for applications requiring a compact, cost-effective high-side switch with integrated protection. Evaluate the 0.7A current limit and 100mΩ on-resistance against load requirements. Consider alternative active models if long-term supply stability is critical for the product lifecycle.

Part Context

This part belongs to Richtek's portfolio of power management integrated circuits (PMICs), specifically within the power distribution switch category. Richtek specializes in PMIC solutions for consumer electronics, telecommunications, and industrial automation, focusing on energy efficiency and precise system control.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the RT9741CGV is obsolete, consult the manufacturer's current product selection guide for equivalent active high-side switches or load drivers.
