S-8253DAD-T8T1S

The S-8253DAD-T8T1S is a configurable power management integrated circuit (PMIC) designed for low power battery management applications. It is designed to provide regulated voltage and current to mobile devices, such as mobile phones and tablets, over a wide input voltage range. This PMIC can be used to manage a single-cell Li-Ion or Li-Polymer battery.

The S-8253DAD-T8T1S consists of a switching buck regulator, a linear battery charger, and power path and high-side switches. It is capable of high-efficiency, low-ripple voltage regulation and supports pulse-width modulation (PWM) and pulse frequency modulation (PFM) control. The device features dual-cell Lithium-Ion and Lithium-Polymer protection, Dynamic power sharing, and over-temperature protection.

The S-8253DAD-T8T1S designt helps to reduce power consumption in battery operated devices, allowing for longer battery life. It is ideal for a range of mobile applications, including smartphone, tablet and wearables. It also supports other portable applications, such as medical devices, laptops, and barcode scanners. The device is also versatile enough for automotive and industrial applications.

The S-8253DAD-T8T1S working principle is based on a buck regulator and a linear voltage regulator. The buck regulator takes a higher input voltage and reduces it to a lower output voltage. It works by connecting an inductor to a battery and switching the input voltage in a pulsed mode. This causes a voltage step down. The linear voltage regulator takes a lower input voltage and adjusts it to a consistent output voltage. It works by controlling the signal flow of a current to the load, which is then used to compare the input with the output.

In addition to voltage and current regulation, the S-8253DAD-T8T1S also supports various protection and safety features. It supports both dual-cell Lithium-Ion and Lithium-Polymer battery protection. It also has over-temperature protection and input over-voltage protection. The integrated power path makes it easy to switch between different power sources, such as the battery and external power. Additionally, the device features Dynamic power sharing, which helps reduce power dissipation and enables efficient power management.

In summary, the S-8253DAD-T8T1S is a PMIC designed for low power battery management applications. It can be used for a variety of mobile applications, such as smartphones, tablets and wearables, as well as for automotive and industrial applications. The key features of the device include a buck regulator, a linear voltage regulator, dual-cell Lithium-Ion and Lithium-Polymer battery protection, Dynamic power sharing, and over-temperature protection. It supports both pulse-width modulation and pulse frequency modulation control for efficient power management.
