Power Management Integrated Circuit (PMIC) is a key device used in many electronic products and systems. The usage of PMIC products has been increasing as technologies become more advanced, and as power consumption is reduced. The S-8200AAG-I6T1U is a type of PMIC specifically designed for battery management applications. This section will discuss the application field and working principle of the S-8200AAG-I6T1U.

Application Field

The S-8200AAG-I6T1U PMIC is designed and optimized for use in battery management applications. It is suitable for single Li-ion/ Li-Polymer cell or a multi cell stack of Li-ion/ Li-Polymer batteries and can operate from 2.7V to 6.5V. The PMIC features an integrated 2A main switch current limiter which can be used for control and management of the load current. It is also equipped with many other features such as built-in charge-discharge-control functions, load regulation, reverse current protection and over-temperature detection for safety. The PMIC also includes a comprehensive set of features for battery management, such as cell balancing, voltage monitoring, and temperature monitoring. The S-8200AAG-I6T1U PMIC is designed to be compliant with the latest safety and regulatory standards and is suitable for use in battery-powered devices.

Working Principle

The working principle of the S-8200AAG-I6T1U PMIC is based on the flow of electrical current through the device. The main components of the PMIC are an integrated 2A main switch current limiter, an integrated 120mV voltage reference, an internal oscillator, and the necessary control circuitry. The PMIC operates by detecting a voltage difference between the load and battery source. When the voltage difference is greater than the reference value, the main switch is triggered, allowing current to flow from the battery to the load.

The current limiter monitors the current flowing through the device and is used to control the load current. If the current exceeds 2A, the current limiter will act to limit further current flow. The voltage reference acts to ensure the battery voltage is always supplied to the load under the specified voltage. The internal oscillator is used to provide a reference frequency for timing and triggering of the main switch. The control circuitry utilizes the voltage reference and oscillator to control and monitor the battery, as well as provide protection to the system.

The S-8200AAG-I6T1U PMIC is designed to regulate the voltage supplied to the load and protect the system from over current and over heating. The PMIC also monitors the voltage and temperature of the battery, and provides safety functions such as cell balancing and reverse current protection. The PMIC can be used with a single Li-ion/ Li-Polymer cell or a multi cell stack of Li-ion/ Li-Polymer batteries, making it a perfect choice for battery management applications.
