Overview
The RT9715FGF is a single-channel N-channel USB power switch manufactured by Richtek USA Inc. It operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 700mA. The device features a typical on-resistance of 90 milliohms and utilizes an SC-74A (SOT-753) surface-mount package. It includes integrated fault protection mechanisms such as fixed overcurrent, thermal shutdown, reverse current blocking, and under-voltage lockout.
Feature Summary
- Integrated high-side N-channel power switch for USB port protection
- Built-in fault protection including overcurrent, thermal shutdown, and reverse current blocking
- Low on-resistance design for efficient power delivery
- Requires no external control voltage supply
Applications
- USB port power switching and protection
- Overcurrent protection for peripheral devices
- Thermal management in portable electronics
Procurement Notes
Verify the specific suffix 'FGF' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Confirm availability status as distribution channels may list obsolete or end-of-life variants.
Selection Notes
Select this component when a compact, low-profile solution is required for USB power management. The SC-74A package suits space-constrained designs. Verify that the 700mA current limit aligns with the connected load requirements and that the 90 milliohm resistance meets efficiency targets.
Part Context
This part belongs to the RT9715 series of USB power switches from Richtek. The series offers various package options and current ratings to suit different application needs. The RT9715FGF specifically provides a balance of protection features and low profile suitable for modern consumer electronics.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Common alternatives in the same family include RT9715DGBG and RT9715BGBR, though pinout and current ratings must be verified.
