RT9715BGBR

Overview

The RT9715BGBR is a single-channel N-channel 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 2A. The device features a typical on-resistance of 90 milliohms and utilizes a SOT-23-5R surface-mount package. It includes comprehensive fault protection mechanisms such as fixed current limiting, overtemperature protection, reverse current blocking, and under-voltage lockout (UVLO). The component functions with a non-inverted input interface and provides status flag indication alongside load release capabilities.

Feature Summary

• Integrated high-side N-channel power switching for USB applications
• Built-in protection against overcurrent, thermal overload, and reverse current flow
• Status flag output for monitoring operational state

Applications

• USB port power distribution
• Load switching in portable electronic devices
• Battery-powered system power management

Procurement Notes

This component is officially listed as End-of-Life (EOL) with a discontinuation date of January 25, 2016. Verification of availability should focus on surplus or obsolete stock channels rather than standard manufacturing supply. Confirm RoHS compliance status and check for valid replacement alternatives from the manufacturer before procurement planning.

Selection Notes

Select this part only if legacy compatibility with the 2.7V to 5.5V operating range and 2A current capacity is required. The SOT-23-5R package limits thermal dissipation compared to larger footprints. Ensure design requirements align with the fixed current limit threshold and that the non-inverted control logic matches the system interface constraints.

Part Context

The RT9715 series represents a family of single-channel power switches designed for low-voltage applications. The BGBR suffix indicates specific pinning and packaging variations within the SOT-23-5R form factor. This component belongs to the broader category of PMIC load drivers used for managing power delivery to peripheral loads in consumer electronics.

Replacement Considerations

As an EOL product, direct substitutes must be verified against pinout compatibility and electrical specifications. Consult official manufacturer cross-reference lists for approved replacements that maintain identical functionality and package dimensions.
