ADP2450ACPZ-5-R7

Power Management - Specialized Overview

The ADP2450ACPZ-5-R7 is a specialized industrial circuit breaker power management unit (PMU) manufactured by Analog Devices Inc. It integrates a boost shunt controller with power detection, a high-efficiency buck regulator, four low-offset programmable gain amplifiers (PGAs), a low-offset operational amplifier, a fast analog trip circuit, and an actuator driver. The device operates within an input voltage range of 4.5 V to 36 V and provides a fixed maximum output voltage of 5 V. It supports continuous output currents up to 500 mA with a quiescent input current of 1.35 mA. Designed for surface-mount installation in LFCSP-32 packages, it functions reliably across temperatures from -40°C to +125°C.

Power Management - Specialized Feature Summary

• Integrates a boost shunt controller with power detection to prevent power hiccups and a high-efficiency buck regulator for stable system power.
• Includes four low-offset, low-power programmable gain amplifiers and a dedicated operational amplifier for precise leakage current detection.
• Features a fast analog trip circuit and actuator driver designed specifically for molded case circuit breaker applications.

Power Management - Specialized Applications

• Low voltage circuit breakers
• Molded case circuit breakers (MCCB)
• Current transformer (CT) powered supply systems

Power Management - Specialized Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the -5 variant corresponds to the fixed 5 V output requirement. Check manufacturer documentation for moisture sensitivity level handling instructions prior to assembly. Ensure the LFCSP-32 footprint matches the target PCB design guidelines provided in the official datasheet.

Power Management - Specialized Selection Notes

Select this component for applications requiring integrated power management and protection logic within compact industrial enclosures. The fixed 5 V output simplifies design compared to adjustable variants. Consider the integrated PGA accuracy for wide-range current measurement needs. Verify that the 500 mA output capability meets the downstream load requirements without external boosting.

Power Management - Specialized Part Context

This part belongs to the ADP2450 family of digital power management ICs tailored for industrial circuit breakers. Unlike general-purpose PMICs, it combines power conversion with sensing and control functions. The ACPZ designation indicates an automotive-grade or extended temperature qualified version in a leadless package. It complements other ADI solutions like the ADP2442 which focuses solely on buck regulation without the integrated trip and sensing features.
