Advanced Digital Power Management
ADI's Advanced Digital Power Technology showcases a cutting-edge setup that seamlessly integrates power management and multi-chemistry battery charging, featuring the ADP1055, LTC4015, and LTC4162. Designed for optimal performance and reliability, this system provides real-time telemetry and diagnostics, ensuring everything runs smoothly. Key highlights include, Digital Power Management and Flexible, Efficient Multi-Chemistry Battery Charging. Together, these elements create a robust and versatile solution for modern power needs, showcasing the future of power technology.
The initial Evaluation board is a Full Bridge Isolated topology using the ADP1055 converting 48V in to 12V out. The ADP1055 is a fully digital secondary side controller with PMBus capability. The 12V output feeds into two digital communications enabled synchronous buck battery chargers.
The LTC4015 is a Multi-Chemistry Step-Down Battery Charger with Power-Path, Telemetry and a Coulomb counter that can support up to 35V with discrete MOSFETs allowing the user to scale power requirements as required. In this application the LTC4015 is configured for a 2cell LiFEPO4 7.2V Battery
LTC4162 is similar charger but being a monolithic solution allows for an overall smaller solution size but with a maximum current output of 3.2A
The LTC4162S is configured for a 6V Lead Acid battery. Each Battery charger output feeds into a LT8640A silent switcher to create 5V, each powering a Raspberry PI which communicates with its respective battery charger via an SMBus interface. Each Raspberry PI’s runs a simple Python GUI which displays on its own respective LCD screen the status of each charger.
By disabling the ADP1055, the 12V input to both battery chargers is removed, which results in each charger, through power path technology seamlessly switching its output from Vin to its respective battery thereby maintain voltage continuously to each respective Raspberry PI. When ADP1055 is reenabled both chargers automatically switch back to 12V in.
