Overview
The RT9702AGJ5 is a high-side power switch manufactured by Richtek Technology Corporation. It features an on-resistance of 80mΩ and supports output currents of 500mA or 1.1A depending on the specific variant configuration. The device operates within a supply voltage range of 2.7V to 6V and includes a status flag output for fault indication. It is housed in a TSOT-23-5 package and is designed for applications requiring compact power distribution solutions with integrated protection features.
Feature Summary
- Integrates a high-side N-channel power switch with low on-resistance for efficient power delivery.
- Includes a dedicated flag pin to provide real-time status indication of the switch state.
- Features built-in protection mechanisms including over-current, thermal shutdown, and reverse current blocking.
Applications
- Power distribution in portable consumer electronics
- Load switching in USB-powered devices
- Battery-powered equipment requiring efficient power management
Procurement Notes
Verify the exact suffix code (e.g., GJ5) against the manufacturer's official datasheet to confirm the specific current rating and package type. Ensure compatibility with the target system's voltage levels and thermal requirements. Cross-reference the part number with authorized distributors to confirm authenticity and availability.
Selection Notes
Select this component when a compact high-side switch with status feedback is required. Compare the 80mΩ resistance and current capabilities against alternative switches to ensure adequate performance margins. Consider the TSOT-23-5 package size constraints and the operating temperature range during the design phase.
Part Context
The RT9702 series belongs to Richtek's portfolio of high-side power switches designed for power distribution ICs. These components are engineered to replace discrete MOSFET solutions, offering integrated protection and reduced board space. The series supports various current ratings to accommodate different load requirements in modern electronic systems.
Replacement Considerations
Consult the official cross-reference list for verified substitutes. Ensure any replacement matches the pinout, voltage rating, and current capacity. Verify that the alternative component maintains similar protection features and package dimensions for direct integration.
