LTC1840CGN#TRPBF

Overview

The LTC1840CGN#TRPBF is a dual fan controller manufactured by Analog Devices Inc., housed in an SSOP-28 package. It features a two-wire serial interface for configuration and control. The device integrates dual automatic PWM fan-speed controllers and includes a two-channel temperature monitor. Designed for thermal management applications, it supports precise cooling regulation through its integrated sensing and control logic.

Feature Summary

• Integrates dual automatic PWM fan-speed controllers for independent channel management
• Includes a two-channel temperature monitor for accurate thermal sensing
• Utilizes a two-wire serial interface for simplified system connectivity and configuration

Applications

• Server and workstation thermal management systems
• Industrial equipment cooling control
• Communication infrastructure thermal regulation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. or its predecessor Linear Technology. Ensure the SSOP-28 package matches your PCB footprint requirements before procurement.

Selection Notes

Select this component when dual-channel fan control with integrated temperature monitoring is required. The two-wire interface reduces pin count compared to parallel interfaces. Verify that the operating voltage range and thermal performance meet the specific application constraints.

Part Context

This part belongs to the LTC1840 series of dual fan controllers. It is functionally similar to parts like the LTC1840CGN and LTC1840IGN, differing primarily in packaging or temperature grade. The series is designed for applications requiring efficient thermal management with minimal external components.

Replacement Considerations

Direct substitutes include LTC1840CGN and LTC1840IGN. Verify pin compatibility and electrical specifications before substitution. Cross-reference with MAX6639 or MAX6640 only if interface and functional differences are acceptable.
