PMIC - Battery Management is a crucial area of Power Management ICs (PMICs). The S-8200ABM-M6T1U is a product within this category which provides system designers with a high-performance battery monitoring and protection solution. The device has both primary and secondary charging paths, as well as a high-voltage comparator for two-level voltage protection and an integrated 3-level power switch for system power supply control. This article explains the application field and working principle of the S-8200ABM-M6T1U.

Application Field

In modern mobile devices, such as computers, tablets, phones and other battery-powered products, a Battery Management System (BMS) is essential to maintain the health and condition of the battery. The S-8200ABM-M6T1U is designed to monitor and protect Li-ion/Li-polymer batteries in such systems. It can detect and alert the user with multiple fault conditions, including discharging over-current, charging overvoltage, over temperature, and low-voltage conditions. It also supports a 2A charging current, with a 14mA safety current that is issued when no fault conditions are detected.

The S-8200ABM-M6T1U can be used in a variety of application fields, including automotive, consumer electronics, energy storage, healthcare, and industrial automation. It’s low-power consumption suitable to use in Energy Harvesting System (EHS) application. This device also provides the benefits of high system reliability and cost-effectiveness, making it an ideal choice for any battery-managed system. Additionally, it adopts 14-pin compact QFN package, which reduces necessary package size on the PCB.

Working Principle

The S-8200ABM-M6T1U is an integrated circuit that includes a battery management and protection function. The device\'s functioning scheme consists of four parts: voltage protection, current protection, heat protection and charging management. The voltage protection tracks battery voltage and will shut off the system output if it exceeds its designed voltage threshold. The current protection monitors and limits both charge and discharge current, protecting the battery from overcharging and over-discharging. The temperature protection shuts off the system when the battery temperature rises beyond its designed temperature threshold. Finally, the charge management section monitors the charger or AC adapter input to the system and issues a regulation current during power up.

The S-8200ABM-M6T1U device utilizes a two-level voltage protection circuit and a high-voltage comparator for the primary charge path protection. It also has a secondary charging path to provide additional safety. An integrated 3-level power switch is used for system power supply control, allowing for a more efficient use of energy and energy flow management. The device\'s optimized control circuit increases the battery usage time and provides greater reliability for users.

The S-8200ABM-M6T1U also features a Multi-State Power Mode Control (MSPMC), which is an operating current control technique. This technique uses temperature and voltage data to adjust operating current to ensure optimal performance while maintaining safety. The device also has a power-on reset function, which automatically resumes the system by detecting the system\'s power-on status. It also has a high-precision thermistor to detect temperature, ensuring accurate temperature detection even under varying environmental conditions.

The S-8200ABM-M6T1U is an advanced PMIC - Battery Management device that is designed to provide superior protection and increased reliability while providing an efficient power supply control. Its optimized design and functionality make it an ideal choice for any battery-managed system. It has a wide range of features, such as voltage protection, current protection, heat protection, charging management, MSPMC, and power-on reset to provide the best possible protection for Li-ion/ Li-polymer batteries in mobile devices.
