PMIC - Battery Chargers are an essential part of mobile electronics, providing a reliable power source to support various requirements of modern gadgets. The ADP3808JCPZ-RL is one such charge controller, with a wide range of applications and a highly efficient working principle.

This charge controller is designed for use with Li-Ion and Polymer batteries, in a variety of single and multi-cell applications. It was designed for use in mobile phones, tablets and portable computing devices like notebooks, for example. It can also be used for industrial applications such as robotics, medical equipment and batteries used for restoring backups in critical systems.

The ADP3808JCPZ-RL has an adjustable charging voltage, with voltage ranges from 2.8V to 4.2V. It also has adjustable current, ranging from 100mA up to 1.1A. The device has a low current quiescent mode, which ensures minimum power consumption when not actively charging. The low power design makes it ideal for long-life applications, where extended battery life is a key concern.

The device also features a wide range of safety features, including over-voltage protection, over-temperature protection, low battery detection, and current-limit detection. This ensures that the battery is protected from overcharging and over-temperature, which can cause permanent damage to the battery and shorten its life significantly. The low battery detection feature enables the system to switch off before the battery voltage drops too low, thus protecting it from permanent damage.

The ADP3808JCPZ-RL utilises a linear regulation principle to charge the battery. This process is based on two transistors, T1 and T2. The transistors switch on and off rapidly at a given rate, relying on the voltage across the load in order to regulate the charging current and maintain the set voltage. This results in high efficiency and low power consumption, making it well suited for applications with high loads and low current input.

The device can also be configured to include a battery-pack feature, allowing for easy replacement of the battery when needed. This feature eliminates the need for system shutdown in order to replace the battery, saving time and money. Additionally, it is compatible with circuit protection devices, ensuring compatibility with a wide range of system designs.

In summary, the ADP3808JCPZ-RL is a highly reliable and efficient charge controller, designed for use with Li-Ion and Polymer batteries. It offers adjustable current and voltage ranges, extensive safety features and a linear regulation charging principle. It is well suited for mobile phones, tablets, laptops and industrial applications such as robotics and medical equipment.
