ADP5091ACPZ-1-R7
Overview
The ADP5091ACPZ-1-R7 is a single-chip energy-harvesting power supply that integrates a boost converter and battery-management functions for small rechargeable cells or supercapacitors. It is intended to extract power from very-low-voltage sources and manage charging and system supply regulation. The device supports multi-chemistry batteries and includes programmable output voltage and fault protections.
Why Choose This Part
This IC combines a boost front end and battery-management in a single package, reducing board space and component count for energy-harvesting designs. It supports multiple battery chemistries and a programmable system voltage, letting engineers tailor behavior to their cell and load. Built-in fault protections such as over-current, over-temperature and short-circuit handling improve system reliability in harsh or unpredictable environments.
Applications
Key Specifications
Getting Started
Start by reading the ADP5091 datasheet and application notes from Analog Devices for recommended input, energy-harvester interface, and layout guidance (including exposed pad thermal land pattern). Use the manufacturer's evaluation board and reference schematic if available to validate harvester source, storage element, and target system load before committing to a PCB layout. Pay close attention to low-leakage layout techniques and the thermal pad soldering/assembly recommendations for reliable operation over the specified temperature range.
