SIP4282DNP3-T1GE4

Overview

The SIP4282DNP3-T1GE4 is a single-channel load switch manufactured by Vishay Siliconix, designed for power distribution applications. It operates within a supply voltage range of 1.8 V to 5.5 V and supports a maximum continuous output current of 1.2 A. The device features an integrated slew rate control mechanism to manage inrush currents during turn-on. Key electrical parameters include a maximum on-resistance (RDS(on)) of 480 mΩ, a typical rise time of 20 µs, and a fall time of 4 µs. It is housed in a compact SC-75-6 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates slew rate control to limit inrush current and reduce stress on upstream power sources.
• Provides low on-resistance for efficient power delivery with minimal voltage drop.
• Operates across a wide input voltage range suitable for various logic levels.

Applications

• Power distribution in portable electronic devices
