Power Management Integrated Circuits (PMICs) - Battery Management

Power Management Integrated Circuits (PMICs) are integrated circuits that are used to manage power supplies in all types of electronics. PMICs generally include devices like DC-DC Converters, Battery Chargers, and Battery Management ICs, all of which are critical components in today’s modern electronic designs. One such PMIC that is gaining increasing use and popularity is the S-8252AAZ-M6T1U.

S-8252AAZ-M6T1U - Application Field and Working Principle

The S-8252AAZ-M6T1U is an ultra-low power and compact rechargeable lithium battery control IC. It is used to manage and control the charging and discharging of rechargeable lithium-ion batteries. This IC is used for general-purpose battery monitoring applications, such as for system power management in portable handheld devices such as cell phones, digital cameras, mp3 players, and PDAs.

The S-8252AAZ-M6T1U contain advanced safety features to maximize protection when charging or discharging batteries like overcurrent protection, overvoltage protection, overheat protection, and short circuit protection. In addition, the S-8252AAZ-M6T1U also features a wide operating temperature range, low power consumption, and high accuracy.

The internal block diagram of the S-8252AAZ-M6T1U consists of three parts: a voltage reference, the voltage converter, and a current sense block. The voltage converter includes an operational amplifier, one P-FET MOSFET, one N-FET MOSFET, and resistors. The current sense block consists of a current sense amplifier, a P-FET MOSFET, and a N-FET MOSFET. The voltage reference is used to monitor the voltage of the battery.

The working principle of the S-8252AAZ-M6T1U is based on a linear control system, where the input is the voltage of the battery, and the output is the current of the battery. The operational amplifier and the two MOSFETs control the voltage applied to the battery in order to control the current. The reference voltage is compared to the real battery voltage, and if the battery voltage is lower than the reference voltage, then the P-FET is turned on and the current is applied to the battery. The same occurs when the battery voltage is lower than the reference voltage, the N-FET will be turned on and the current will be taken out from the battery. The current sense block monitors the amount of current that is flowing through the battery so that the circuit can prevent overcharging or over discharging.

The S-8252AAZ-M6T1U is designed as a highly efficient and cost-effective alternative for managing rechargeable lithium-ion batteries, and has minimal power consumption. It is a popular choice for battery management systems in many types of portable-electronic devices, such as cell phones, PDAs, and digital cameras. As the demand for portable electronics increases, so too will the demand for efficient battery management systems, and the S-8252AAZ-M6T1U is well-positioned to take advantage of this growing demand.
