Overview
The SIP32452DB-T2-GE1 is a single-channel high-side load switch manufactured by Vishay Siliconix. It operates within an input voltage range of 0.9 V to 2.5 V and features a typical on-resistance (Rds(on)) of 55 mΩ. The device supports a continuous output current of 1.2 A with a maximum turn-on time of 1 µs. It is housed in a compact WCSP-4 package, suitable for surface-mount applications. The component functions as a power distribution switch with integrated reverse current protection.
Feature Summary
- Integrated reverse current protection prevents backflow from the load side.
Applications
- Portable electronic devices requiring low-voltage power management
- Battery-powered systems utilizing high-side switching
- Power distribution networks in consumer electronics
Procurement Notes
Verify the specific suffix T2-GE1 against the manufacturer's latest datasheet to confirm package type and environmental compliance status. Ensure the operating voltage requirements align with the 0.9 V to 2.5 V specification before integration. Cross-reference the marking code AB for identification accuracy during assembly.
Selection Notes
Select this component for applications requiring low on-resistance and fast switching speeds within a 2.5 V supply limit. The WCSP-4 package offers a small footprint ideal for space-constrained designs. Consider the 1.2 A current rating when sizing thermal solutions, although the low power dissipation may reduce cooling requirements.
Part Context
This part belongs to the SIP3245x series of load switches from Vishay Siliconix. These components are designed for efficient power distribution in portable electronics. The series typically includes variants with different resistance and voltage ratings, sharing common packaging and protection features like reverse current blocking.
Replacement Considerations
Check for direct substitutes within the SIP3245x family that match the 55 mΩ Rds(on) and 1.2 A current rating. Verify pin compatibility and package dimensions (WCSP-4) for any alternative parts. Ensure replacement components support the same 0.9 V to 2.5 V operating range and reverse current protection functionality.
