SIP32432DNP3-T1GE4

Overview

The SIP32432DNP3-T1GE4 is a high-side load switch featuring a p-channel MOSFET with slew rate control and reverse blocking capability. It operates within an input voltage range of 1.5 V to 5.5 V, supporting continuous currents up to 1.4 A. The device utilizes a TDFN-4 package measuring 1.2 mm by 1.6 mm. Key electrical parameters include a typical on-resistance of 135 mΩ at 3 V and 105 mΩ at 5 V. It exhibits ultra-low leakage, with static current typically at 10 pA at 3.3 V. The component supports logic low-level enable control and functions across a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix 'T1GE4' against the manufacturer's official documentation to confirm tape and reel specifications and RoHS compliance status. Ensure the ordering information matches the exact TDFN-4 package dimensions and pinout configuration required for the target PCB layout. Cross-reference the active lifecycle status directly with Vishay Siliconix to avoid obsolescence risks during production planning.

Selection Notes

Select this component when reverse blocking functionality is required without additional bias rails. The logic low enable signal suits systems where active-low control signals are standard. The low on-resistance minimizes power loss in high-current paths. Consider the compact TDFN-4 footprint for space-constrained designs requiring efficient thermal dissipation and minimal board area usage.

Part Context

This part belongs to the SiP3243x family of load switches designed for low-power applications. It shares architectural similarities with the SiP32431 but differs in enable logic polarity. The series targets portable electronics needing precise power sequencing and protection. The TDFN-4 package provides a balance between thermal performance and size reduction compared to larger DFN options.

Replacement Considerations

SiP32431DNP3-T1GE4 requires logic high enable; verify interface compatibility.
