Battery management is a complicated process which requires a vast amount of engineering expertise in order to ensure that a battery is being handled correctly, lasts for its intended lifetime, and operates safely and efficiently. Power management integrated circuits (PMICs) are designed to optimize this process and ensure that large or small battery-powered applications keep going for as long as possible. In this article, we will take a look at the LTC6803IG-2#PBF device and describe its application field and working principle.

Overview of the LTC6803IG-2#PBF PMIC

The Linear Technologies LTC6803IG-2#PBF is one of the latest additions to the family of Power Management Integrated Circuits (PMICs). This PMIC includes a battery monitoring system which is incredibly beneficial for battery-powered applications. The LTC6803IG-2#PBF is designed for monitoring, managing, and protecting large and small Li-ion and Li-polymer batteries. It comes with a low profile 2mm x 3mm QFN package and a set of eight wires which is quite convenient for the battery pack assembly.

Application Fields of the LTC6803IG-2#PBF

LTC6803IG-2#PBF, with its battery protection features, is perfect for critical applications such as automotive and aerospace. Whenever a large or small Li-ion battery pack is involved, the LTC6803IG-2#PBF PMIC works hard to make sure the battery pack is continually being monitored, managed, and protected.

Apart from automotive and aerospace use, the LTC6803IG-2#PBF can also be used in the field of portable instrumentation, computer and consumer electronics, medical diagnostics and wearable devices. Depending on the application, the PMIC can easily be configured in protection mode, monitoring mode, or a combination of both.

Working Principle of the LTC6803IG-2#PBF

The LTC6803IG2#PBF operates in either voltage or current mode, depending on the requirements of the application. The PMIC works by monitoring the battery pack and providing feedback about the status of the pack battery. This feedback includes the pack voltage, current, temperature, and charge status. In case of an overvoltage, undervoltage, over temperature, or overcurrent condition, the PMIC can either notify the user or cut off the power to the application to protect the battery pack.

The LTC6803IG2#PBF features two sets of desulfator circuits to prevent the battery pack from being damaged due to prolonged storage. This PMIC also includes a pre-charge state, where it can charge up the battery pack in order to bring its Terminal Voltage (Vt) up to its minimum value.

This PMIC also comes with built-in interface commands for battery protection metrics, including the voltage, current, temperature, total charge, and timeouts. This allows the PMIC to be configured to turn on or off devices, discharge or charge a certain battery cell, or to apply a certain voltage or current.

Conclusion

The LTC6803IG-2#PBF PMIC is an ideal solution for larger battery packs used in applications such as automotive, aerospace, portable instrumentation, medical diagnostics, and more. This PMIC can monitor, manage, and protect battery packs, and provide feedback on pack voltage, current, temperature, and charge. It also features two sets of desulfator circuits to help prevent the battery pack from being damaged due to prolonged storage. With its wide range of features and low profile 2mm x 3mm QFN package, this PMIC is set to become an invaluable tool for managing battery-powered applications.
