LTC1422IS8#PBF

Hot Swap Controllers Overview

The LTC1422IS8#PBF is an 8-pin hot-swap controller designed for safe insertion of external peripherals into device bay slots. It operates with an input voltage range of 2.7V to 12V and draws a supply current of 650 µA. The device supports automatic retry, undervoltage lockout (UVLO), and programmable features including circuit breaker settings, fault timeouts, and slew rate control. It is housed in an SOIC-8 surface-mount package and functions within a temperature range of 0°C to +70°C.

Hot Swap Controllers Feature Summary

• Enables safe insertion and removal of peripheral cards by controlling power-up sequencing and limiting inrush current.
• Provides integrated protection mechanisms including adjustable current limit, thermal shutdown, and fault timeout detection.
• Supports automatic retry functionality to restore power after transient faults without requiring manual intervention.

Hot Swap Controllers Applications

• Power solutions for DB32, DB20, and DB13 device bays
• Safe insertion of external peripherals into equipment slots
• General-purpose hot-swap controller applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix IS8 against official Analog Devices documentation to confirm the SOIC-8 package and industrial temperature rating. Ensure compatibility with system voltage requirements between 2.7V and 12V. Confirm that the 650 µA supply current aligns with low-power design constraints. Validate pinout alignment for the 8-pin configuration during PCB layout. Cross-reference the part number with manufacturer datasheets to avoid confusion with similar hot-swap controllers.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring controlled power-up sequences for hot-pluggable modules. It is suitable for applications needing built-in fault protection and automatic recovery capabilities. Consider the SOIC-8 package size for space-constrained layouts. Evaluate the need for programmable slew rates to minimize electromagnetic interference during startup. Ensure the operating temperature range meets the environmental conditions of the target deployment.

Hot Swap Controllers Part Context

The LTC1422 belongs to Analog Devices' family of hot-swap controllers, which are specialized power management ICs. These devices are engineered to protect both the host system and the inserted card from electrical stress during connection. The IS8 variant specifically denotes the surface-mount SOIC-8 packaging option, distinguishing it from through-hole DIP versions like the CN8.
