LTC4261IGN#TRPBF

Hot Swap Controllers Overview

The LTC4261IGN#TRPBF is a hot swap controller manufactured by Analog Devices Inc., designed for -48V applications. It features an integrated ADC and I2C interface for monitoring. The device supports programmable characteristics including auto-retry, current limiting, fault timeout, latch-off fault protection, overvoltage protection (OVP), and undervoltage lockout (UVLO). It operates within a temperature range of -40°C to +85°C and consumes 2 mA of supply current. The component is housed in a 28-SSOP package with a width of 3.90mm.

Hot Swap Controllers Feature Summary

• Integrates an analog-to-digital converter for precise voltage and current monitoring capabilities
• Supports I2C communication interface for digital control and status reporting
• Provides comprehensive protection mechanisms including overvoltage, undervoltage lockout, and latch-off fault handling

Hot Swap Controllers Applications

• -48V telecommunications systems
• Industrial equipment requiring hot swap functionality
• Server backplanes

Hot Swap Controllers Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation, as the provided model includes a TRPBF suffix which may differ from the standard IGN#TR designation found in some distributor listings. Confirm availability status directly with the manufacturer or authorized distributors, as supply constraints have been noted for this product line. Ensure the specific ordering code matches your design requirements before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when designing systems that require robust hot swap protection for -48V rails. The integrated ADC allows for detailed system monitoring without external sensors. Consider the 28-SSOP package size for board space constraints. Verify that the I2C interface compatibility aligns with the host microcontroller or processor in the design architecture.

Hot Swap Controllers Part Context
