LTC4240CGN#PBF

Hot Swap Controllers Overview

The LTC4240CGN#PBF is a compact hot-swap controller designed for Compact PCI bus applications. It enables safe insertion and removal of boards from live slots. The device features an integrated two-wire I2C compatible interface for software control and monitoring of power supply status. It supports output voltages of -12V, 3.3V, 5V, and 12V. The component is housed in a 20-lead SSOP package.

Hot Swap Controllers Feature Summary

• Enables safe board insertion and removal from live Compact PCI bus slots
• Integrates a two-wire I2C compatible interface for system control
• Facilitates software monitoring of device function and power supply status

Hot Swap Controllers Applications

• Hot-swap controllers for Compact PCI bus systems
• Software-controlled power management for live bus slots
• Monitoring power supply status in Compact PCI environments

Hot Swap Controllers Procurement Notes

Verify the specific suffix PBF to confirm lead-free compliance and RoHS standards. Ensure the SSOP-20 package matches the target PCB footprint. Confirm compatibility with the required I2C bus voltage levels and the supported output voltage rails (-12V, 3.3V, 5V, or 12V) for the intended Compact PCI application.

Hot Swap Controllers Selection Notes

Select this component when designing for Compact PCI hot-swap requirements. The built-in I2C interface allows for detailed system integration and remote monitoring. Consider the SSOP-20 package size constraints. Verify that the specific voltage rail requirements align with the supported outputs. This controller is optimized for Compact PCI rather than other bus standards like PCIe.

Hot Swap Controllers Part Context

This part belongs to the Analog Devices LTC4240 series of hot-swap controllers. It is specifically engineered for Compact PCI applications, distinguishing it from other series members designed for different bus architectures. The series focuses on providing robust protection and control for live bus insertion scenarios.

Hot Swap Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-reference options based on pinout compatibility, I2C interface support, and Compact PCI specific voltage ratings.
