Description and Introduction
0.3-25V; high frequency switch mode Li-Ion battery charger. For portable computers, fast chargers The ADP3806JRU-12.5 is a battery charger controller IC manufactured by Analog Devices (AD). It is designed for use in single-cell lithium-ion (Li-ion) or lithium-polymer (Li-poly) battery charging applications. The device operates with an input voltage range of 4.5V to 28V and provides a constant current/constant voltage (CC/CV) charging profile. It features a programmable charging current up to 1.25A and includes thermal regulation to prevent overheating. The ADP3806JRU-12.5 is available in a 20-lead TSSOP package and is specified for operation over the industrial temperature range of -40°C to +85°C. It also includes safety features such as battery temperature monitoring and charge termination based on current detection.
