Introduction

Power Management IC (PMIC) is a key component in many electronic systems that is responsible for managing, distributing, monitoring and optimizing power within the system. PMICs play a critical role in controlling how much power is consumed, how it is distributed and the overall quality of the power that is provided to the system.The S-8244AAGFN-CEGT2G is a PMIC from Japanese semiconductor manufacturer Seiko Epson Corporation that is designed for lithium-ion and lithium-polymer battery-powered products. It provides over-voltage protection and under-voltage protection while measuring charge and discharge currents up to 1.5A.

Application Field

The S-8244AAGFN-CEGT2G is used in a variety of applications including mobile phones and tablet PCs, wearable devices such as smart watches, remote controllers, wireless gaming controllers and electronic toys. Its power management capabilities make it an ideal solution for battery-powered applications, where extended battery life and reliable operation are essential.Other applications include medical device power supplies, drones and drones equipment, industrial applications, automotive applications and communication systems.

Features

The S-8244AAGFN-CEGT2G provides a range of features for battery management, including over-voltage protection, discharge over-current protection, and charge over-current protection. It also offers low operating current, programmable under-voltage protection, and temperature protection. It is designed with safety protection in mind, including reverse current protection, handling shocks, and a ‘safe time-out’ that prevents the system from unexpectedly shutting down due to an unexpected over-current or over-temperature situation. The S-8244AAGFN-CEGT2G is available in a space-saving 45-pin VQFN package that fits easily into 8 x 8 mm space, while also offering maximum versatility.

Working Principle

The S-8244AAGFN-CEGT2G is suited for Li-ion/Li-polymer battery protection, it is able to measure the charge and discharge current up to 1.5A. In order to protect the battery, the device offers over-voltage protection, under-voltage protection (UVLO) and temperature protection.The over-voltage protection is to prevent the battery from being overcharged and damaged, by monitoring the system\'s battery voltage. Once the threshold is reached, the device interrupts the charging current to avoid damages and it will resume charging only when the voltage is below the threshold.Under-voltage protection is used to detect if the battery voltage falls below the specified threshold, which indicates that the battery is discharged below its safe level. This will then stop further discharge current to prevent permanent damage to the battery. Temperature protection is used to maintain a safe operating temperature range for the device. If any of the temperatures exceed the pre-defined limits set by the user (or the device) then the charge/discharge process will be interrupted and the device will enter a safe mode.

Conclusion

The S-8244AAGFN-CEGT2G is a PMIC from Seiko Epson Corporation that is designed for lithium-ion and lithium-polymer battery-powered products. It offers over-voltage protection, under-voltage protection, and temperature protection. The chip is suitable for a wide range of applications, including mobile phones and tablet PCs, wearable devices, remote controllers, wireless gaming controllers, electronic toys, industrial applications, automotive applications, communication systems and medical device power supplies. It also comes in a space-saving 45-pin VQFN package. As such, the S-8244AAGFN-CEGT2G is the perfect solution for battery powered applications.
