LTC4261CGN#PBF

Hot Swap Controllers Overview

The LTC4261CGN#PBF is a negative voltage hot swap controller manufactured by Analog Devices Inc. It integrates an analog-to-digital converter (ADC) and I2C monitoring capabilities within a 28-lead SSOP package. The device operates with a supply current of 2 mA and supports automatic retry, overvoltage protection, undervoltage lockout, and fault timeout features. Designed for -48V systems, it provides precise control over power-up and power-down sequences while monitoring rail parameters via the digital interface.

Hot Swap Controllers Feature Summary

• Integrates an ADC for real-time monitoring of voltage and current parameters
• Supports I2C communication for digital configuration and status reporting
• Includes programmable fault handling with automatic retry and lockout mechanisms

Hot Swap Controllers Applications

• -48V telecommunications infrastructure
• Industrial control systems requiring hot swap capability
• Telecom equipment power distribution units

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'CGN' against official Analog Devices documentation to confirm temperature range and package specifications. Ensure compatibility with existing PCB footprints for the 28-SSOP package. Confirm that the I2C address and register map align with system requirements before integration.

Hot Swap Controllers Selection Notes

Select this component when negative voltage hot swap protection is required alongside digital monitoring. The integrated ADC allows for precise threshold setting without external comparators. Consider the 28-SSOP package size relative to available board space. Verify that the operating temperature range meets the environmental conditions of the target application.

Hot Swap Controllers Part Context

This part belongs to the LTC4261 family of hot swap controllers designed for managing power insertion in sensitive electronic systems. The series offers various package options and feature sets to accommodate different design constraints. The CGN variant specifically denotes commercial temperature range performance within the standard SSOP form factor.

Hot Swap Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the LTC4261 series such as the LTC4261IGN#TR or LTC4261CUFD-2#PBF. Verify that any substitute maintains identical I2C functionality and thermal characteristics.
