RT9712AGF

Overview

The RT9712AGF is a dual high-side power switch IC manufactured by Richtek Technology Corporation. It integrates two N-MOSFET channels 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 features an internal charge pump for gate drive control without external components. Key electrical parameters include a 1A/1.5A current rating per channel, reverse blocking capability, and under-voltage lockout. The component is housed in a compact SOT-23-6 package.

Feature Summary

• Integrates two independent high-side N-MOSFET switches with low on-resistance for efficient power distribution.
• Incorporates an internal charge pump to control rise and fall times, minimizing current surges during switching.
• Provides comprehensive protection including reverse blocking current, under-voltage lockout, and short-circuit handling.

Applications

• Power distribution systems requiring multiple switches in a single package
• Applications involving heavy capacitive loads
• Short circuit protection scenarios

Procurement Notes

Verify the specific suffix AGF against the official Richtek datasheet to confirm pinout and package compatibility. Confirm end-of-life status and lead times through authorized distributors. Ensure RoHS compliance documentation is available for your region. Cross-reference ordering numbers carefully as suffixes may indicate packaging variations rather than functional differences.

Selection Notes

Select this component when space-constrained designs require dual high-side switching capabilities. It is suitable for applications needing surge current management via internal charge pump control. Consider the 90mΩ on-resistance for thermal performance in high-current paths. Verify input voltage stability remains above the under-voltage lockout threshold during operation.
