LTC1623CMS8#TRPBF

Overview

The LTC1623CMS8#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 MSOP-8 package. The device operates on a supply voltage range of 2.7 V to 5.5 V. Key electrical characteristics include a rise time of 1 µs and a fall time of 300 ns. It supports a maximum input voltage of 5.5 V and functions reliably within an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates dual high-side MOSFET gate drivers with dedicated control logic
• Features an SMBus serial interface for configuration and monitoring
• Provides independent control over two high-side switches

Applications

• SMBus-controlled power distribution units
• Hot-swap controller applications requiring dual channels
• System power management modules

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the CMS8 designation corresponds to the commercial temperature grade and MSOP-8 footprint required for your design. Ensure compatibility with the 2.7 V to 5.5 V supply range during procurement planning.

Selection Notes

Select this component when a dual-channel high-side switching solution with digital control is required. It is suitable for designs needing SMBus integration rather than discrete GPIO control. Consider the MSOP-8 package constraints and the specific rise and fall times for signal integrity requirements in your layout.

Part Context

This part belongs to the LTC1623 series of high-side switch controllers from Analog Devices. It serves as a specialized power management IC designed for systems requiring controlled power sequencing or protection via a serial bus interface, distinct from standard operational amplifiers or regulators in the manufacturer's portfolio.
