RT9724GB

Overview

The RT9724GB is a cost-effective, low-voltage, single N-MOSFET high-side power switch IC manufactured by Richtek USA Inc. It operates within an input voltage range of 2.7 V to 5.5 V and supports a continuous current limit of 2 A. The device features a typical on-resistance of 100 mΩ and a maximum on-resistance of 120 mΩ. Supply current is typically 50 µA. Switching characteristics include a maximum on-time of 3 ms and a maximum off-time of 4 µs. It is housed in an SOT-23-5 package (SC-74A/SOT-753).

Feature Summary

Single N-channel MOSFET high-side power distribution switch design.
Integrated slew rate control for load switching applications.
Low supply current consumption for energy-efficient operation.

Applications

Power distribution switches in portable devices.
Load drivers for low-voltage digital systems.
Battery-powered equipment requiring efficient power management.

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm the specific suffix 'GB' matches your board requirements. Note that this part may be obsolete; check for active status before finalizing procurement plans. Ensure all handling and storage conditions comply with industry standards for surface-mount devices.

Selection Notes

Select this component when a single high-side switch with controlled slew rate is required. Verify that the 2 A current limit and 5.5 V maximum input voltage align with system specifications. Consider the SOT-23-5 package size for PCB layout constraints. Evaluate thermal performance based on the expected load current and ambient temperature conditions.

Part Context

The RT9724 series belongs to Richtek's portfolio of power management solutions designed for portable electronics. These components focus on providing efficient power distribution with minimal footprint. The RT9724GB specifically targets applications needing reliable high-side switching with built-in protection features inherent to modern power switch ICs.

Replacement Considerations
