SC824ULTRT Integrated Circuits (ICs)

PMIC - Battery Chargers

The SC824ULTRT is a power management integrated circuit (PMIC) specially designed for use in advanced battery charging applications. It is a combination of a full analogue front-end with integrated power management and digital power management technologies. This PMIC can be used to provide current and voltage regulation for advanced battery charging applications, allowing for improved battery cycle life, better charge accuracy, and improved power efficiency.

The SC824ULTRT is a two-phase switch mode-pulse width modulation (PWM) battery charger with a digital signal processor (DSP) for integrated power management. It is designed to provide a fast and accurate charge to various battery types with a wide input voltage range. The combination of closed loop control and switched capacitor (SC) DC/DC power conversion make the SC824ULTRT an efficient and reliable powering solution.

Application Field

The SC824ULTRT has a wide range of applications, including but not limited to mobile phones, digital cameras, portable medical and fitness devices, power tools, wearable technology, and automotive, aviation, and marine applications. The SC824ULTRT can also be used for backlight management, general-purpose DC/DC conversion, and post-regulation/load balancing.

Working Principle

The SC824ULTRT uses switched capacitor (SC) power conversion, which is a more efficient version of traditional board-level switching power conversion. The power conversion is based on a two-phase, synchronous buck converter with pulse-width modulation (PWM) for precise regulation. This offers improved efficiency and reduced electromagnetic interference (EMI). The digital signal processor (DSP) allows for accurate control and monitoring of all current, voltage, temperature and safety parameters.

The SC824ULTRT features a second buck converter to provide additional power for applications such as backlight management and general-purpose DC/DC conversion. The SC824ULTRT also features internal protection circuitry, including over-voltage, over-current, and thermal shutdown. The device also features a range of programmable current, voltage, and time settings to optimize battery performance, cycle life, and charge accuracy.

Overall, the SC824ULTRT is a highly efficient and reliable battery charging solution that provides improved charge accuracy, cycle life, and power efficiency. Its wide range of applications and programmable settings make it ideally suited for advanced battery charging applications in mobile, automotive, and industrial equipment.
