SIP32432DR3-T1GE3

Overview

The SIP32432DR3-T1GE3 is a high-side power switch IC from Vishay Siliconix, featuring reverse blocking capability and low static current. It operates within an input voltage range of 1.5 V to 5.5 V and supports continuous currents up to 1.4 A. The device utilizes a p-channel MOSFET with typical on-resistance values of 105 mΩ at 5 V and 135 mΩ at 3 V in the TDFN4 package. It includes programmable slew rate control for turn-on time, logic low enable control, and ultra-low leakage characteristics.

Feature Summary

• Reverse blocking functionality eliminates the need for external series diodes
• Ultra-low static and leakage currents suitable for battery-powered applications
• Programmable slew rate control manages inrush current during turn-on
• Logic low enable control allows direct interface with microprocessors

Applications

• Wireless sensor networks
• Smart meters
• Wearable devices
• Portable medical equipment
• Battery-powered instruments

Procurement Notes

Verify that the specific suffix DR3 corresponds to the SC-70-6 package configuration when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation. Ensure the logic low enable requirement aligns with system control voltages. Check for automotive qualification variants if operating in harsh environments.

Selection Notes

Select this component for applications requiring reverse blocking protection without additional bias rails. The low static current makes it ideal for energy-constrained systems. Verify that the 1.4 A continuous current rating meets load requirements. Consider the SC-70-6 package size constraints against available PCB space.

Part Context

This part belongs to the SiP3243x family of smart load switches designed for portable electronics. It integrates protection features typically found in more complex power distribution units into a compact surface-mount package. The device simplifies design by combining switching and protection functions.

Replacement Considerations

SIP32431DR3-T1GE3 offers identical electrical specifications but uses logic high enable control instead of logic low.
