LTC4253BCGN#PBF

Hot Swap Controllers Overview

The LTC4253BCGN#PBF is a hot swap controller designed for -48V systems, manufactured by Analog Devices Inc. It operates within a supply voltage range of -48V and features a single channel configuration. The device is housed in a 16-SSOP package with a width of 0.154 inches (3.90mm). It supports surface mount installation and functions within an operating temperature range of 0°C to 70°C. The component draws a supply current of 1.1 mA and does not include internal switches.

Hot Swap Controllers Feature Summary

• Programmable circuit breaker functionality for precise current limiting
• Integrated overvoltage protection (OVP) and undervoltage lockout (UVLO)
• Configurable fault timeout settings for system reliability
• Latched fault mechanism to secure system state during errors

Hot Swap Controllers Applications

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

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'B' against official Analog Devices documentation to confirm exact electrical tolerances and performance grades. Confirm the 'CGN' package designation matches the required 16-SSOP footprint. Ensure compatibility with -48V system architectures before integration. Check for any recent product change notifications that may affect pinout or specifications.

Hot Swap Controllers Selection Notes

Select this component for applications requiring robust protection in negative voltage environments. The programmable features allow customization of current limits and fault responses. Consider the absence of internal switches when designing the external MOSFET drive circuit. Evaluate the latched fault behavior to determine if it aligns with the system's recovery strategy.
