Overview
The ADM1278-1ACPZ-RL is a hot swap controller and power monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5V to 20V and features a single channel configuration housed in a 32-LFCSP (5x5) package. The device supports PMBus interface for programmable control, including automatic retry, current limiting, fault timeout, and overvoltage protection. It functions reliably across an operating temperature range of -40°C to 85°C with a typical supply current of 5.5 mA.
Feature Summary
- Integrates hot swap control with comprehensive power monitoring capabilities via PMBus interface
- Supports programmable protection features including automatic retry, current limiting, and fault lockout
- Enables precise voltage regulation and system protection through configurable overvoltage and undervoltage lockout thresholds
Applications
- General purpose hot swap controller applications
- System power management and monitoring
- Server and data communication equipment protection
Procurement Notes
Verify component status as the ADM1278-1ACPZ-RL is listed as obsolete or end-of-life by the manufacturer. Confirm availability of alternative sources or qualified replacement parts before finalizing procurement plans. Ensure compatibility with existing design specifications when sourcing from secondary markets.
Selection Notes
Select this component for applications requiring integrated hot swap control and power monitoring in a compact surface-mount package. Consider the PMBus interface for digital control requirements. Evaluate thermal performance within the specified operating temperature range and ensure adequate layout for the LFCSP footprint.
Part Context
This part belongs to the ADM1278 series of low-voltage positive hot swap controllers with power monitoring. It is designed for protecting circuits during insertion and removal from live backplanes. The series emphasizes precision monitoring and robust protection mechanisms for sensitive electronic systems.
Replacement Considerations
The ADM1281-1ACPZ-RL is identified as an available substitute for the ADM1278-1ACPZ-RL. Verify pin compatibility and functional equivalence before implementation.
