Overview
The RT9711CGB is an 80mΩ, 0.6A high-side power switch with a flag output, designed for USB applications. It features a typical RDS(ON) of 80mΩ in the SOT-23-5 package and supports input voltages from 2.5V to 5.5V. The device offers low quiescent current (25μA on, 1μA off), soft-start for hot-plug capability, and comprehensive protection including UVLO, current limiting, thermal shutdown, and reverse current blocking.
Feature Summary
- Compliant with USB specifications for portable and bus-powered applications
- Integrated N-MOSFET with low on-resistance and open-drain fault flag
- Soft-start functionality enables safe hot-plug-in operations
- Built-in protections against over-current, overheating, and under-voltage
Applications
- Universal Serial Bus (USB) powered devices
- Bus-powered peripheral equipment
- Portable battery-operated electronics
Procurement Notes
Verify the specific suffix 'GB' against official Richtek documentation, as standard listings typically cite 'J5' for TSOT-23-5 or 'B' for SOT-23-5. Confirm lead-free status and RoHS compliance directly with the manufacturer or authorized distributor. Ensure the package type matches the required PCB footprint before ordering.
Selection Notes
Select this component for designs requiring compact high-side switching with minimal board space. The 0.6A continuous load current suits low-power USB peripherals. Consider the TSOT-23-5 or SOT-23-5 package for size constraints. Evaluate the 80mΩ on-resistance for voltage drop requirements within the 2.5V to 5.5V input range.
Part Context
The RT9711 series comprises high-side power switches tailored for USB applications. Variants include A/B (1.5A) and C/D (0.6A) current ratings. The RT9711CGB belongs to the 0.6A subset, offering integrated protection and low standby current. It is part of Richtek's portfolio for efficient power management in consumer electronics.
Replacement Considerations
Check for direct substitutes within the RT9711 family, such as RT9711DGS or RT9711CPJ5, ensuring identical current ratings and package compatibility. Verify pinout and electrical characteristics match before substitution.
