Description and Introduction

0.4-18V; 500mW; secondary, off-line battery changer controller. For battery changer controlled for: lilon batteries (ADP3810) NiCad, NiMH batteries (ADP3811) The ADP3810AR-4.2 is a linear charger controller IC manufactured by Analog Devices (AD). It is designed for single-cell lithium-ion (Li-ion) battery charging applications. The key specifications include:

- **Output Voltage:** 4.2V (fixed)
- **Charging Current:** Programmable via an external resistor
- **Input Voltage Range:** 4.5V to 28V
- **Operating Temperature Range:** -40°C to +85°C
- **Package:** 8-lead SOIC
- **Charge Termination:** Automatic charge termination based on battery voltage and current
- **Protection Features:** Overvoltage protection, thermal shutdown, and reverse battery protection
- **Control Method:** Constant current/constant voltage (CC/CV) charging

This IC is typically used in portable electronics, such as smartphones, tablets, and other devices requiring single-cell Li-ion battery charging.
