LTC1623IS8#TRPBF

Overview

The LTC1623IS8#TRPBF is a dual high-side switch controller manufactured by Analog Devices Inc. It integrates two MOSFET gate drivers and an SMBus interface within an 8-lead SOIC package. The device operates from a single supply voltage ranging from 2.7V to 5.5V. It features independent control of each channel, allowing for precise management of external N-channel power MOSFETs. The component supports standard SMBus communication protocols for configuration and status monitoring.

Feature Summary

• Integrates dual high-side gate drivers with integrated level shifting for driving external N-channel MOSFETs
• Includes an on-chip SMBus interface for serial control, configuration, and fault reporting
• Provides independent channel control with programmable dead-time and current limit settings

Applications

• Power distribution systems requiring remote switching and monitoring
• Industrial equipment with multiple load protection requirements
• Telecommunications infrastructure power management units

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the IS8 variant meets industrial temperature range specifications required for your application environment. Ensure compatibility with your system's SMBbus clock speeds and voltage levels before finalizing procurement plans.

Selection Notes

Select this component when dual isolated high-side switching with digital control is necessary. It is suitable for designs requiring individual channel current limiting and fault detection via a serial interface. Consider the SOIC-8 footprint constraints and the need for external N-channel MOSFETs compatible with the driver output capabilities.
