ADP5063ACPZ-1-R7 Integrated Circuits (ICs)

PMIC - Battery Chargers

ADP5063ACPZ-1-R7 is a linear battery charger which is designed to fast charge single-cell Li-Polymer, Li-Ion, or LiFePO4 batteries from an AC adapter. It is a low drop-out, low noise, current-mode charger for single or multi-cell battery applications. It offers integrated short-circuit protection and overvoltage protection, and it can handle input voltages up to 6.5V with a maximum charging current of up to 1.25A.

The application field of this particular charger includes single-cell Li-Polymer, Li-Ion and LiFePO4 battery-based products such as portable devices, handheld devices and medical equipment. The battery charger is suitable for various applications including Internet of Things (IoT) applications, audio systems, and other electronic systems requiring Li ion/Li-Polymer/LiFePO4 battery power. It is suitable for charging sealed as well as unsealed battery chemistries.

Working Principle

ADP5063ACPZ-1-R7 is a linear battery charger which uses the low drop-out and low noise techniques. The charger has a built-in over-temperature protection and short-circuit protection which protect the battery from over charging and thermal runaway. When connected to the input AC adapter, the charger automatically detects the input voltage and currents and adjusts its output charging current accordingly. The charger also features an auto-recovery feature which enables it to resume charging after a power drop.

The charger has two light-emitting diodes to indicate the charging status. The green LED will light up when the charger has detected the battery voltage, and the red LED will light up when the battery voltage has reached its target level. The charger also has an internal charge current sensor which allows it to detect the battery temperature and limits its charging current when the temperature reaches a critical level to ensure safe operation.

The charger also has an integrated safety timer and trickle-charging feature which prevents the battery from being overcharged and increases its life time. The trickle-charge feature ensures that the battery voltage remains constant at the end of the charging cycle and prevents self-discharge. The safety timer also reduces the risk of thermal runaway and prevents the battery from being overcharged for an extended period.
