Power management integrated circuits (PMICs) are essential in a wide range of electronic systems. As the demand for smaller and lighter products increases, manufacturers must use highly efficient and reliable PMICs to meet these requirements.

The S-8211CDK-I6T1U is a power management integrated circuit (PMIC) designed specifically for battery management applications. It is a single-chip, pulse-width modulation (PWM) controller that provides power control and a power-on reset (POR) function, as well as over-temperature and over-voltage lockout protection. It offers flexibility, low power consumption and superior reliability, making it an ideal solution for various battery management applications.

Application Field

The S-8211CDK-I6T1U is suitable for a variety of battery management applications, including notebook computer and tablet PCs, portable media players, mobile phones, digital cameras, pocket PCs, and other handheld consumer electronics. It can regulate both primary (charger) and secondary (battery) power sources, and is therefore ideal for applications in which a single power source is used for both charging and running the application. It is also suitable for power control applications in which two or more power sources are used in a single system.

The S-8211CDK-I6T1U can provide regulated output voltage with high accuracy, low quiescent current, and controlled power on/off sequencing. This makes it an ideal solution for powering high-performance systems, such as those found in notebook computers, tablet PCs, and digital cameras.

The S-8211CDK-I6T1U is also widely used in battery management applications, such as portable media players, mobile phones, and digital cameras. It provides a reliable and cost-effective solution for these and other consumer electronics applications.

Working Principle

The S-8211CDK-I6T1U features a low-power PWM control IC, which can provide an efficient and reliable power supply for applications requiring a single or multiple voltage rails. It includes an on-board voltage controller to provide adjustable output voltage levels and a Power-On Reset (POR) circuit to prevent system lock-up when the power source is changed, as well as over-temperature and over-voltage lock-out protection.

As with most PWM controllers, the S-8211CDK-I6T1U operates by modulating the output voltage with a fixed frequency, usually in the range of 500 to 5000 kHz, depending on the application. The output voltage is determined by the duty cycle of the PWM signal, which is determined by the control circuitry in the IC. The control circuitry in the IC allows the output voltage to be set to a pre-determined level, and it will automatically adjust the duty cycle of the PWM signal in order to maintain that voltage level.

The S-8211CDK-I6T1U also includes power on reset (POR) and over-temperature protection, which are essential for reliable battery management. The POR feature ensures that the system is in a known power-up state, even after a power source change. The over-temperature protection prevents the system from overheating and provides safe and reliable power control.

In order to ensure efficient and reliable power management for portable and consumer electronics applications, the S-8211CDK-I6T1U is ideal for single and multiple voltage rail solutions. It provides an efficient and reliable power supply and is capable of providing adjustable output voltage levels, as well as power on reset and over-temperature protection.
