• Built-in thermal shutdown and over-current protection enhance system reliability.
• Low quiescent current (40μA typical) and shutdown current (<1μA) help extend battery life.
• Logic-controlled enable input with fast turn-on and turn-off times.
• Available in compact SOT-23-5 package for space-constrained designs.

Applications

• Smartphones and tablets
• Wearable devices
• Portable electronics
• Industrial control systems
• Power distribution switches

Selection Guidance

When selecting the RT9746WSC, verify the input voltage range and maximum load current against your system requirements. The device is optimized for low-voltage applications; for higher voltage or current needs, consult the full Richtek load switch portfolio. Ensure proper PCB layout for thermal performance, and refer to the datasheet for detailed specifications and application circuits.
