SIP32419DN-T1-GE4

Overview

The SIP32419DN-T1-GE4 is a smart load switch IC manufactured by Vishay Siliconix, designed for power distribution applications. It operates within a supply voltage range of 6 V to 28 V and supports a continuous output current of 4.5 A. The device features a low on-resistance of 56 mΩ maximum and includes programmable current limiting adjustable from 750 mA to 3.5 A. Key timing parameters include a maximum turn-on time of 550 µs and a maximum idle time of 1 µs. It is housed in a DFN-10 surface-mount package with a maximum power dissipation of 1.42 W and functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates programmable current limit functionality allowing adjustment between 750 mA and 3.5 A
• Features controlled slew rate management with defined turn-on and idle times
• Provides high-side switching capability with low on-resistance for efficient power distribution

Applications

• Power distribution systems requiring intelligent load protection
