LTC1422CN8#PBF

Hot Swap Controllers Overview

The LTC1422CN8#PBF is a single-channel hot-swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 12V and draws a typical supply current of 650 µA. The device is housed in an 8-pin PDIP package with a standard lead pitch of 0.300 inches (7.62mm). It supports through-hole mounting and functions across an operating temperature range of 0°C to +70°C. Key electrical features include programmable circuit breaker, fault timeout, and slew rate controls.

Hot Swap Controllers Feature Summary

• Integrates programmable circuit breaker functionality for precise overcurrent protection during insertion events.
• Features adjustable slew rate control to manage inrush current and prevent bus voltage droop.
• Includes automatic retry capability to recover from transient fault conditions without manual intervention.
• Provides undervoltage lockout (UVLO) to ensure stable operation under low supply voltage conditions.

Hot Swap Controllers Applications

• Safe insertion of external peripherals into device bay slots
• PCI Express card edge power management
• General-purpose hot-swap system protection

Hot Swap Controllers Procurement Notes

Verify the specific suffix CN8 corresponds to the 8-pin PDIP package configuration. Confirm RoHS compliance status via official documentation. Ensure the operating environment remains within the specified 0°C to +70°C range. Validate that the application voltage does not exceed the 12V maximum limit. Check for any recent product change notifications affecting pinout or specifications.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution is required for general-purpose hot-swap applications. It is suitable for systems needing adjustable inrush control and automatic fault recovery. Consider the PDIP package for through-hole prototyping or high-reliability board designs. Evaluate if the 650 µA supply current meets low-power standby requirements.

Hot Swap Controllers Part Context

This part belongs to the LTC1422 family of hot-swap controllers designed for safe peripheral insertion. It serves as a dedicated power management IC for protecting system buses during module insertion and removal. The device simplifies design by integrating control logic, sensing, and protection circuits into a single compact package.
