Description and Introduction

±1% Precision, Single Cell Li-Ion Battery Charger The ADP3820ART-4.2RL7 is a linear battery charger IC manufactured by Analog Devices (AD). It is designed for single-cell lithium-ion (Li-ion) or lithium-polymer (Li-poly) batteries. The device features a preset 4.2V charging voltage, making it suitable for standard Li-ion/Li-poly battery chemistries. It includes thermal regulation to prevent overheating and supports a constant-current/constant-voltage (CC/CV) charging algorithm. The ADP3820ART-4.2RL7 operates with an input voltage range of 4.25V to 6.5V and has a typical charging current of 500mA. It comes in a small 6-lead TSOT package, making it suitable for space-constrained applications. The device also includes built-in safety features such as overvoltage protection and battery temperature monitoring.
