RT9712AGS

Overview

The RT9712AGS is a dual high-side power distribution switch from Richtek Technology Corporation, designed for heavy capacitive loads and short circuit protection. It integrates two N-MOSFET switches with a total on-resistance of 90mΩ per channel. The device operates within a supply voltage range of 2.7V to 5.5V and supports output currents up to 1.5A. An internal charge pump eliminates the need for external components while controlling rise and fall times to minimize current surges. It features under-voltage lockout and status flags, packaged in an 8-SOP (SOIC) case.

Feature Summary

• Dual high-side N-MOSFET power switches integrated into a single package
• Internal charge pump for gate drive control without external components
• Status flag output for monitoring switch conditions
• Under-voltage lockout protection mechanism

Applications

• Power distribution systems requiring multiple switches
• Heavy capacitive load applications
• Short circuit protection circuits

Procurement Notes

Verify the specific suffix 'GS' against the manufacturer's official datasheet to confirm the 8-SOP package and pinout configuration. Ensure compatibility with the required 2.7V to 5.5V operating voltage range. Confirm that the 90mΩ on-resistance meets the thermal and efficiency requirements of the target application. Check for RoHS compliance status in the latest documentation.

Selection Notes

Select this component when dual independent high-side switching is required in a compact form factor. The internal charge pump simplifies design by removing external bootstrap components. Suitable for low-voltage DC-DC conversion or peripheral power management where surge current limiting and fault indication are necessary. Verify that the 1.5A current rating aligns with the load requirements.

Part Context

The RT9712 series belongs to Richtek's power management IC portfolio, specifically targeting general-purpose power distribution. It complements single-channel variants like the RT9711 by offering dual functionality. The AGS designation typically indicates the specific package type and temperature grade, distinguishing it from other suffixes in the family.

Replacement Considerations

Direct substitutes include the RT9711 series for single-channel applications or other dual switches from Richtek such as the RT9712AGE if package differences are acceptable. Verify pin-to-pin compatibility before substitution.
