ADP2450ASTZ-5-R7

Power Management - Specialized Overview

The ADP2450ASTZ-5-R7 is a specialized digital power management IC designed for industrial circuit breaker applications. It integrates a boost shunt controller with power detection, a high-efficiency buck regulator, four programmable gain amplifiers (PGAs), a low-offset operational amplifier, an analog trip circuit, and an actuator driver. The device operates within an input voltage range of 4.5 V to 36 V, delivering a fixed maximum output voltage of 5 V at up to 500 mA. It features a fixed switching frequency of 1.2 MHz and functions across temperatures from -40°C to +125°C.

Power Management - Specialized Feature Summary

• Integrates a boost shunt controller with programmable power detection to prevent power hiccups in CT-powered systems.
• Includes a high-efficiency buck regulator with PWM mode operation for low output ripple voltage.
• Features four low-offset, low-power programmable gain amplifiers for accurate wide-range current measurement.
• Contains an integrated analog trip circuit and actuator driver for direct protection control.

Power Management - Specialized Applications

• Low voltage molded case circuit breakers (MCCB)
• Current transformer (CT) powered supply systems
• Industrial circuit breaker power management

Power Management - Specialized Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to restricted availability status. Confirm package integrity upon receipt as the part utilizes surface-mount technology. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference datasheet revisions to guarantee compatibility with existing design specifications.

Power Management - Specialized Selection Notes

Select this variant when a fixed 5 V output is required for downstream logic or sensor powering. Consider the LQFP-48 package for thermal performance and pin accessibility. Evaluate the integrated PGA accuracy against specific current sensing requirements. Verify that the 500 mA continuous output capability meets the load demands of the target circuit breaker application.

Power Management - Specialized Part Context

This component belongs to the ADP2450 family of dedicated power management ICs. Variants differ primarily by output voltage configuration and package type, such as the LFCSP-32 or LQFP-48 options. The series targets the niche market of intelligent electrical protection devices requiring compact, integrated power and signal conditioning solutions.
