ADM1278-1AACPZ-RL

Overview

The ADM1278-1AACPZ-RL is a hot swap controller and power monitor manufactured by Analog Devices Inc. It features a single channel with an operating supply voltage range of 4.5V to 20V. The device is housed in a 32-LFCSP (5x5) package and supports surface mount installation. Key electrical characteristics include a supply current of 5.5 mA and an operating temperature range from -40°C to +85°C. It integrates programmable features such as auto-retry, current limiting, fault timeout, latch-off fault, overvoltage protection, slew rate control, and UVLO.

Feature Summary

• Integrates hot swap control with comprehensive power monitoring capabilities for single-channel applications.
• Supports PMBus interface for digital communication and configuration.
• Includes programmable protection features such as auto-retry, current limiting, and overvoltage protection.
• Features internal circuitry for fault timeout and latch-off fault management.

Applications

• General purpose hot swap controller applications
• Power monitoring systems requiring PMBus integration

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Check for specific manufacturing date codes if required for legacy system compatibility. Ensure compliance with RoHS3 specifications during procurement planning.

Selection Notes

Select this component for designs requiring integrated hot swap control and power monitoring in a compact LFCSP package. Consider the 4.5V to 20V input range and 5.5mA supply current for power budget calculations. Verify that the single-channel architecture meets system requirements compared to multi-channel alternatives.

Part Context

This part belongs to the ADM1278 series of hot swap controllers from Analog Devices. It is designed for general-purpose applications requiring robust power path management. The device complements other PMIC solutions by providing precise control and monitoring via PMBus.

Replacement Considerations

The ADM1281-1ACPZ-RL is listed as an available substitute for the discontinued ADM1278-1ACPZ-RL. Verify pinout and functional compatibility before implementation.
