ADM1294-1BACPZ-RL7

Overview

The ADM1294-1BACPZ-RL7 is a digital power monitor featuring an integrated PMBus interface, designed for low-side supply monitoring. It operates within a supply voltage range of 2.95 V to 13 V and supports current supply up to 3.6 mA. The device utilizes a 16-lead LFCSP package (4mm x 4mm) and functions across an operating temperature range of -40°C to 105°C. Its architecture includes an integrated shunt regulator, enabling power delivery and supply monitoring across wide voltage ranges suitable for single-phase metering applications.

Feature Summary

• Integrates a PMBus interface for digital communication and control
• Features an internal shunt regulator for self-powering during monitoring
• Supports low-side supply monitoring configurations
• Designed for single-phase energy metering environments

Applications

• Single-phase energy metering systems
• Low-side DC power supply monitoring
• Digital power management via PMBus
• Industrial equipment power supervision

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the AC designation aligns with the required industrial temperature grade (-40°C to 105°C). Ensure the LFCSP-16 footprint matches the target PCB design. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs. Validate that the PMBus implementation meets system communication requirements.

Selection Notes

Select this component for applications requiring precise low-side current and voltage monitoring with digital feedback. The integrated shunt regulator simplifies board layout by eliminating external bias supplies. Consider the 16-lead LFCSP package for compact surface-mount implementations. Verify that the PMBus protocol satisfies the host controller's communication needs. Ensure the operating voltage range covers the monitored rail's maximum limits.
