Procurement Notes
Verify component status as the RT9715EGB is listed as obsolete and no longer manufactured by Richtek USA Inc. Confirm availability through authorized distributors or secondary market sources if procurement is required. Ensure replacement strategies account for end-of-life status when designing new products.
Selection Notes
Select this component for applications requiring a cost-effective, low-voltage high-side switch with USB compatibility. Consider the 1.1A current limit and 90mΩ on-resistance for thermal and efficiency requirements. Evaluate alternative active components if long-term supply stability is critical due to the obsolete status.
Part Context
The RT9715EGB belongs to Richtek's line of power distribution switches and load drivers. It is part of the RT9715 family, which includes variants like the RT9715GGB. These devices are engineered for analog power management tasks, specifically focusing on efficient load switching and protection in consumer electronics.
Replacement Considerations
Consult official datasheets for cross-reference candidates such as the RT9711CGB or other industry-standard power switches. Verify pinout compatibility and electrical specifications before substitution. No direct substitute is confirmed in public documentation; engineering validation is required.
