It is designed to protect and manage Li-Ion and Li-Polymer Battery Packs and is applicable to various rechargeable battery types. The APM8601FB-7 is a multi-functional battery charging and monitoring solution that offers high accuracy and superior reliability.

Features of APM8601FB-7

The APM8601FB-7 has a range of features that make it an ideal choice for battery management and protection. It supports an adjustable charge current from 0.1A (minimum) to 1A (maximum) and features an LED indicator to indicate status of the charge cycle. The APM8601FB-7 is also capable of Volumetric Efficiency Testing (VET) for Li-Ion batteries with two-point calibration for accurate results. It also supports an auto-recharge function, which automatically re-charges the battery when it reaches a given threshold. The APM8601FB-7 is designed with overcharge protection and temperature regulation features to ensure safe and reliable operation.

Working Principle of APM8601FB-7

The APM8601FB-7 employs a constant voltage and constant current charging technique. When the battery is initially connected, the IC monitors the battery voltage and current and attempts to maintain a constant voltage until the current drops below the set point. The charge current is then adjusted to maintain a constant current until the battery is fully charged. The APM8601FB-7 also includes an auto-recharge function that recharges the battery once the voltage reaches a pre-determined threshold. When the battery is connected to the IC for charging, the IC begins to monitor the battery voltage. When the voltage reaches a voltage threshold, the IC automatically kicks in to regulate the current according to the voltage. This ensures that the charge cycle is safe and efficient. The APM8601FB-7 features an adjustable temperature regulation, which helps protect the battery from overcharging and over-temperature. This feature will also shut off the current in case of any unexpected occurrences and ensure longer life of the battery.
