ADM1278-3ACPZ-RL

Hot Swap Controllers Overview

The ADM1278-3ACPZ-RL is a hot swap voltage controller and power monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5V to 20V and features a 32-LFCSP (5x5) surface-mount package. The device integrates programmable protection mechanisms including automatic retry, current limiting, fault timeout, overvoltage protection, and undervoltage lockout. It supports PMBus communication for configuration and monitoring. The component functions as a general-purpose hot swap controller with an internal switchless design, suitable for managing power insertion in electronic systems.

Hot Swap Controllers Procurement Notes

Verify the component status carefully before procurement as this part is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that any replacement components are fully compatible with the original design specifications. Check for product change notices regarding manufacturing process updates or final time buy options. Validate that the specific suffix matches the required package and tape-and-reel configuration for your assembly line.

Hot Swap Controllers Selection Notes

Select this component when a hot swap controller with PMBus capability and integrated protection logic is required. Consider the 32-LFCSP package size for space-constrained designs. Evaluate the operating temperature range and supply voltage requirements against system constraints. Verify compatibility with existing firmware if PMBus integration is planned. Assess whether the lack of an internal switch meets the application's power path requirements.

Hot Swap Controllers Part Context

The ADM1278 series belongs to Analog Devices' portfolio of hot swap voltage controllers designed for safe board insertion and removal from live backplanes. These devices provide comprehensive protection against electrical faults during power-up and short-circuit conditions. The ADM1278-3ACPZ-RL specifically offers a fixed configuration variant within this family, emphasizing ease of integration for standard power management tasks in industrial and commercial equipment.

Hot Swap Controllers Replacement Considerations

Public documentation identifies the ADM1281-1ACPZ-RL as a substitute part number for the ADM1278 series. Verify pinout and functional compatibility before substitution.
