LTC4261CGN-2#PBF

Hot Swap Controllers Overview

The LTC4261CGN-2#PBF is a negative voltage hot swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of -12 V to -100 V and supports a single channel. The device features an adjustable current limit and includes an integrated ADC for monitoring via I2C. It functions with a quiescent current of 2 mA and is rated for operation between 0°C and +70°C. The component is housed in a 28-lead SSOP package.

Hot Swap Controllers Feature Summary

• Integrates an analog-to-digital converter for real-time system monitoring
• Supports communication through an I2C interface
• Provides adjustable current limiting capabilities

Hot Swap Controllers Applications

• Negative voltage hot swap control systems
• I2C monitored power distribution networks
• Telecommunications equipment requiring -48V management

Hot Swap Controllers Procurement Notes

Verify the specific suffix designation, as variants such as the TRPBF indicate tape-and-reel packaging while the PBF suffix denotes tube packaging. Confirm that the required operating temperature range aligns with the commercial grade specifications. Ensure compatibility with the target negative voltage rail before procurement.

Hot Swap Controllers Selection Notes

Select this component when managing negative voltage rails up to -100 V with precise monitoring requirements. The integrated ADC allows for detailed fault analysis without external sensors. Consider the SSOP package constraints for board layout and thermal dissipation needs relative to the application's power density.

Hot Swap Controllers Part Context

This part belongs to the LTC4261 family of hot swap controllers designed for negative voltage applications. It complements other series members like the LTC4263, which targets positive voltage Power Sourcing Equipment standards. The device serves as a critical interface for protecting sensitive loads during insertion or removal events.
