Overview
The SIP32454DB-T2-GE1 is a single-channel load switch from Vishay Siliconix, designed for power distribution applications. It operates within a supply voltage range of 800 mV to 2.5 V and features a maximum on-resistance of 35 mΩ. The device supports an output current of 1.2 A with a maximum turn-on time of 1.2 ms and a maximum turn-off time of 1 µs. It is housed in a WCSP-4 package suitable for surface mount installation and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates controlled slew rate management to limit inrush current during startup
- Provides compact surface-mount packaging optimized for space-constrained designs
- Features low on-resistance for efficient power delivery with minimal voltage drop
Applications
- Portable electronic devices requiring efficient power switching
- Battery-powered systems needing low quiescent current operation
- Embedded circuits utilizing low-voltage logic interfaces
Procurement Notes
Verify the specific suffix T2-GE1 against the manufacturer's latest datasheet to confirm package type and RoHS compliance status. Ensure the input voltage does not exceed the 2.5 V maximum rating to prevent device damage. Confirm thermal dissipation requirements align with the specified power dissipation limits under expected operating conditions.
Selection Notes
Select this component when a low-voltage (up to 2.5 V) single-channel switch is required. The 35 mΩ on-resistance balances conduction losses with cost. Consider the 1.2 A current limit for downstream protection needs. The WCSP-4 package is suitable for high-density PCB layouts where small footprint is critical compared to larger packages.
Part Context
This part belongs to the SIP32454 series of load switches from Vishay Siliconix. These components are engineered for portable electronics and battery-operated equipment. The series offers various configurations tailored for different voltage levels and current capacities, providing integrated protection and control features for modern power management architectures.
Replacement Considerations
Consult official substitution guides for equivalent single-channel load switches with similar voltage ratings and current capabilities. Verify pin compatibility and electrical parameters before replacing.
