LTC4253IGN#PBF

Hot Swap Controllers Overview

The LTC4253IGN#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 16-SSOP package. The device supports surface mount installation and functions as a single-channel controller without internal switches. Key programmable protections include circuit breaker, current limit, fault timeout, overvoltage protection (OVP), and under-voltage lockout (UVLO). It offers latched fault handling and draws 1.1 mA of supply current.

Hot Swap Controllers Feature Summary

• Provides comprehensive protection for -48V hot swap applications through programmable circuit breaker and current limit settings.
• Includes advanced fault management with latched fault capability and configurable fault timeout parameters.
• Integrates overvoltage protection (OVP) and under-voltage lockout (UVLO) to ensure system stability during power anomalies.

Hot Swap Controllers Applications

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

Hot Swap Controllers Procurement Notes

Verify the specific suffix IGN against official Analog Devices documentation to confirm package type and temperature rating. Confirm availability status as product lifecycle stages may affect supply. Ensure compatibility with -48V system requirements before integration. Cross-reference pinouts with the latest datasheet to avoid design errors.

Hot Swap Controllers Selection Notes

Select this component for designs requiring robust protection in -48V environments without integrated power switches. Evaluate the need for latched fault behavior versus auto-retry mechanisms. Consider the 16-SSOP footprint constraints relative to board space. Verify that external switch selection matches the controller's drive capabilities and thermal requirements.

Hot Swap Controllers Part Context

This part belongs to the LTC4253 family of hot swap controllers from Analog Devices. It is distinct from variants with internal switches or different voltage ratings. The IGN suffix typically denotes an industrial temperature range and SSOP packaging. It serves as a critical interface between the power source and load in high-reliability systems.

Hot Swap Controllers Replacement Considerations

Check for direct substitutes within the LTC4253 series such as LTC4253CGN#PBF for commercial temperature ranges. Verify functional equivalence regarding pinout and protection thresholds. Consult Analog Devices for updated recommendations if the part is obsolete.
