LTC1422IN8#PBF

Hot Swap Controllers Overview

The LTC1422IN8#PBF is a single-channel hot-swap controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7 V to 12 V and features a supply current of 650 µA. The device is housed in an 8-pin PDIP package with a standard pitch of 0.300 inches (7.62 mm). It supports through-hole mounting and functions across a temperature range of 0°C to +70°C. Key programmable characteristics include circuit breaker settings, fault timeout durations, and voltage slew rate control. The component includes automatic retry functionality and under-voltage lockout (UVLO) for robust power management.

Hot Swap Controllers Feature Summary

• Enables safe insertion and removal of peripheral cards into live backplanes or system slots
• Provides programmable control over inrush current limiting via adjustable slew rates
• Integrates automatic retry mechanisms to restore power after transient fault conditions

Hot Swap Controllers Applications

• Safe insertion of external peripherals into device bay slots
• Power solutions for equipment racks such as DB32, DB20, and DB13
• General-purpose hot-swap voltage control in industrial systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix IN8 against official documentation to confirm the PDIP package type and leaded construction. Ensure the operating environment remains within the specified 0°C to +70°C range. Confirm that the 2.7 V to 12 V input voltage window aligns with the target system design requirements before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when a through-hole solution is required for hot-swap applications. The 8-pin DIP format facilitates prototyping and manual assembly. Consider the 650 µA supply current for low-power standby requirements. Verify compatibility with the target board layout regarding the 0.300-inch pin spacing.

Hot Swap Controllers Part Context

This part belongs to the LTC1422 series of hot-swap controllers from Analog Devices. It serves as a general-purpose solution for managing power delivery during card insertion events. The IN8 designation specifically identifies the PDIP package variant, distinguishing it from surface-mount options like the MSOP or SOIC packages available in the same product family.

Hot Swap Controllers Replacement Considerations

The DC1357A is a demonstration board associated with the LTC1422 series, not a direct functional replacement. No other public substitute part numbers are confirmed for this specific component.
