RT9712BGS

Overview

The RT9712BGS is a dual high-side power switch from Richtek Technology Corporation, designed for heavy capacitive loads and short circuit protection. It integrates two 90mΩ N-MOSFETs in an 8-SOP package. The device operates within a supply voltage range of 2.7V to 5.5V. An internal charge pump provides gate drive without external components, minimizing current surges during switching. Key features include reverse blocking current capability and under-voltage lockout.

Feature Summary

• Integrates two 90mΩ N-MOSFET switches for efficient power distribution
• Internal charge pump eliminates need for external components
• Controls rise and fall times to minimize current surges
• Includes reverse blocking current and under-voltage lockout

Applications

• Power distribution systems requiring multiple switches
• Applications with heavy capacitive loads
• Short circuit protection circuits

Procurement Notes

Verify the exact suffix 'BGS' against official Richtek documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage ranges and thermal requirements. Confirm RoHS compliance status through manufacturer declarations. Check for any specific handling instructions related to moisture sensitivity levels before assembly.

Selection Notes

Select this component when a compact solution for dual high-side switching is required. The integrated charge pump simplifies design by removing external driver components. Consider the 90mΩ on-resistance for efficiency calculations. Verify that the 2.7V minimum operating voltage aligns with the system's power rail capabilities.

Part Context

This part belongs to the RT9712 series of power-distribution switches. It is manufactured by Richtek Technology Corporation. The device is specifically engineered to handle demanding load conditions while maintaining low on-resistance. It serves as a robust solution for modern power management architectures.

Replacement Considerations

RT9711AGB: Single switch variant with 80mΩ resistance. RT9711A: Dual switch variant with different current ratings. Verify pinout and functional equivalence before substitution.
