SIP32451DB-T2-GE1

Overview

The SIP32451DB-T2-GE1 is a low input voltage load switch manufactured by Vishay Siliconix. It operates within a supply voltage range of 0.9 V to 2.5 V and features a typical on-resistance (RON) of 55 mΩ. The device supports an output current of 1.2 A and utilizes a 4-WCSP package with dimensions of 0.76x0.76 mm. Key electrical characteristics include fast turn-on time, low logic control with hysteresis, and reverse current blocking when disabled.

Feature Summary

• Provides reverse current blocking functionality when the device is in the disabled state.
• Features low logic control inputs equipped with hysteresis for stable switching operation.
• Designed for low input voltage applications ranging from 0.9 V to 2.5 V.

Applications

• Portable electronic devices requiring efficient power distribution
• Battery-powered systems utilizing low voltage rails
• Embedded circuits needing compact load switch solutions

Procurement Notes

Verify the specific ordering suffix and tape/reel configuration against the manufacturer's latest documentation before procurement. Ensure that the WCSP-4 package footprint matches the design layout. Confirm RoHS compliance status and lead-free specifications as required by project standards. Cross-reference the datasheet revision date to ensure all electrical parameters are current.

Selection Notes

Select this component for designs requiring a compact N-channel load switch with low on-resistance and reverse blocking capabilities. It is suitable for applications where space is limited due to its small WCSP-4 package. Consider the 0.9 V to 2.5 V operating range to ensure compatibility with the system's power rail. The fast turn-on time makes it appropriate for systems requiring quick power sequencing.
