RT9712DGS

Overview

The RT9712DGS is a dual high-side power distribution switch manufactured by Richtek Technology Corporation. It integrates two N-channel MOSFETs with a typical on-resistance of 90mΩ, designed for heavy capacitive loads and short-circuit protection. The device operates within a supply voltage range of 2.7V to 5.5V and includes an internal charge pump for gate drive control without external components. Key electrical parameters include a reverse blocking current specification and under-voltage lockout functionality. It is housed in an SOP-8 surface-mount package.

Feature Summary

• Integrates two 90mΩ N-MOSFET switches for efficient power distribution
• Internal charge pump eliminates the need for external components
• Includes flag output for status indication
• Provides protection against reverse blocking current and under-voltage conditions

Applications

• Power distribution systems requiring multiple switches in a single package
• Applications involving heavy capacitive loads
• Systems requiring short-circuit protection capabilities

Procurement Notes

Verify the specific suffix DGS against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with operating voltage ranges and thermal requirements. Confirm RoHS compliance status through manufacturer declarations before integration into final products.

Selection Notes

Select this component when dual high-side switching is required in a compact form factor. The integrated charge pump simplifies design by removing external driver components. Consider the 90mΩ on-resistance for efficiency calculations and ensure the SOP-8 package fits the available PCB space constraints.

Part Context

This part belongs to the RT9712 series of power-distribution switches from Richtek. The series is engineered to handle demanding load conditions while minimizing current surges during switching transitions. It serves as a solution for consolidating multiple power paths into a single integrated circuit.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may not match the specific internal charge pump characteristics or flag pin configurations.
