ADP5092ACPZ-1-R7

Overview

The ADP5092ACPZ-1-R7 is an ultra-low power energy harvesting PMU from Analog Devices, designed for converting DC power from photovoltaic cells or thermoelectric generators. It integrates a boost regulator with MPPT, charge management, and voltage monitoring in a 24-pin LFCSP package. The device operates with input voltages from 80 mV to 3.3 V and provides a regulated output current of up to 150 mA within the 1.5 V to 3.6 V range. It features cold start capability down to 380 mV and supports charging lithium-ion batteries, thin-film batteries, supercapacitors, and traditional capacitors.

Feature Summary

• Integrates maximum power point tracking (MPPT) functionality in both dynamic detection and non-detection modes to optimize energy extraction.
• Features ultra-low static current consumption of 450 nA during operation and 360 nA in hysteresis mode for enhanced efficiency at light loads.
• Includes programmable charge management and voltage monitoring to protect rechargeable storage elements and manage power paths.
• Supports temporary shutdown of the boost regulator via microcontroller communication to minimize interference during RF transmission.

Applications

• Photovoltaic (PV) cell energy harvesting systems
• Thermoelectric generator (TEG) energy harvesting applications
• Self-powered wireless sensor devices
• Industrial monitoring equipment powered by ambient energy

Procurement Notes

Verify the specific suffix -R7 indicates reel packaging when ordering. Confirm the -1 variant matches the required output configuration against the official datasheet. Check for moisture sensitivity labeling as the component requires proper handling. Ensure the 24-pin LFCSP footprint aligns with the PCB design guidelines provided in the manufacturer's documentation before finalizing procurement.

Selection Notes

Select this component for applications requiring sub-microwatt quiescent currents and integrated MPPT from low-voltage sources like PV or TEG. It is suitable for systems needing simultaneous boost conversion and battery charging without external controllers. Consider the 150 mA output limit and 80 mV minimum input requirement when sizing the energy harvester. Verify compatibility with the target storage element type, such as lithium-ion or supercapacitors, based on the programmable thresholds.
