SIP32453DB-T2-GE1

Overview

The SIP32453DB-T2-GE1 is a single-channel smart load switch manufactured by Vishay Siliconix. It operates within a supply voltage range of 0.8 V to 2.5 V and supports a continuous output current of 1.2 A. The device features a maximum on-resistance of 55 mΩ, ensuring efficient power delivery. Key timing parameters include a maximum turn-on time of 1.2 ms and a maximum turn-off time of 1 µs. It is housed in a compact WCSP-4 package with dimensions of 0.76 mm x 0.76 mm. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates slew rate control to limit inrush current during startup
• Provides reverse current blocking capability for bidirectional protection
• Features low on-resistance for minimized power dissipation

Applications

• Portable electronic devices requiring efficient power distribution
• Battery-powered systems needing controlled load switching
• Consumer electronics utilizing low-voltage power rails

Procurement Notes

Verify the specific suffix T2-GE1 against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the target PCB footprint, specifically the WCSP-4 package dimensions. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-voltage, single-channel load switch with integrated inrush control is required. It is suitable for applications where space is limited due to its small WCSP-4 package. Consider the 1.2 A current rating and 55 mΩ resistance for thermal management. Compare with other SIP3245x series variants if different current or resistance specifications are needed.
