ADP5091ACPZ-2-R7

Overview

The ADP5091ACPZ-2-R7 is a nano power management unit (PMU) from Analog Devices, designed for energy harvesting applications. It integrates an ultra-low quiescent current boost converter with integrated Maximum Power Point Tracking (MPPT), charge management capabilities, and input power monitoring. The device supports lithium-ion battery charging and manages power paths for small electronic devices. It features a wide input voltage range of 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. Packaged in a 24-pin LFCSP, it operates between -40°C and +125°C.

Feature Summary

• Integrates MPPT functionality for efficient energy extraction from photovoltaic or thermoelectric sources
• Features ultra-low static current consumption for minimal energy loss during operation
• Includes programmable charge management and power path control for battery protection
• Supports cold start operation at very low input voltages via internal charge pump

Applications

• Photovoltaic (PV) cell energy harvesting systems
• Thermoelectric generator (TEG) energy harvesting
• Self-powered wireless sensor nodes
• Industrial monitoring equipment
• Portable and wearable devices with energy harvesting capabilities

Procurement Notes

Verify the specific suffix 'R7' indicates reel packaging when ordering. Confirm the '-2' variant designation matches the required pinout or feature set compared to other ADP5091 models. Ensure compatibility with the target PCB footprint for the LFCSP-24 package. Check for moisture sensitivity level requirements during assembly.

Selection Notes

Select this component for designs requiring sub-microwatt standby power and integrated MPPT. Suitable for environments with fluctuating input voltages from solar or thermal sources. Consider the 150 mA output limit for load requirements. Evaluate the need for external components based on the desired output voltage programming options.

Part Context

This part belongs to the ADP5091 family of nano PMUs. It shares core architecture with variants like the ADP5091ACPZ-1-R7 but may differ in specific configuration pins or default settings. The family targets ultra-low power IoT and sensor applications where maintenance-free operation is critical.

Replacement Considerations

Direct substitutes include other ADP5091 variants such as ADP5091ACPZ-1-R7, provided functional differences are acceptable. Cross-reference pinouts and electrical specifications carefully before substitution.
