Description and Introduction

High Frequency Switch Mode Dual Li-Ion Battery Chargers The ADP3802AR is a battery charger controller IC manufactured by Analog Devices Inc. (ADI). It is designed for single-cell lithium-ion (Li-ion) or lithium-polymer (Li-poly) battery charging applications. Key specifications include:

- **Input Voltage Range**: 4.5V to 28V
- **Charging Voltage Accuracy**: ±1%
- **Charge Current Accuracy**: ±5%
- **Programmable Charge Current**: Up to 2A
- **Battery Voltage Regulation**: 4.1V or 4.2V (selectable)
- **Thermal Regulation**: Yes
- **Operating Temperature Range**: -40°C to +85°C
- **Package**: 8-lead SOIC

The ADP3802AR integrates a PWM controller, charge current sensing, and thermal regulation to ensure safe and efficient battery charging. It also includes features like under-voltage lockout (UVLO) and over-temperature protection.
