SIP32455DB-T2-GE1

Overview

The SIP32455DB-T2-GE1 is a single-channel load switch IC from Vishay Siliconix, designed for power distribution applications. It operates within a supply voltage range of 800 mV to 2.5 V and supports a maximum continuous current limit of 1.2 A. The device features a typical on-resistance of 35 mOhms and a maximum turn-on time of 1.2 ms. It includes an idle time specification of up to 1 us. The component is housed in a WCSP-4 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides controlled slew rate management for load switching applications
• Supports low-voltage operation down to 800 mV
• Integrates current limiting protection with a 1.2 A threshold

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing efficient power distribution
• Embedded circuits managing peripheral power sequencing

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 the WCSP-4 package footprint aligns with your PCB layout guidelines. Confirm RoHS compliance status through official documentation before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that require precise control over power-up slew rates to minimize inrush current. The low on-resistance makes it suitable for maintaining efficiency in low-voltage domains. Consider the 1.2 A current limit when sizing for potential transient loads in portable or battery-operated equipment.
