The RT9750WSC PMIC (Power Management Integrated Circuit) is a specialist charger designed to charge single-cell LiPo batteries reliably and efficiently. It is amongst the most advanced chips available in its field, offering a wide array of features to ensure the reliability and safety of charging. With its high current output, advanced management features, and high precision current and voltage monitoring, it is the perfect solution for single-cell LiPo battery applications.

The RT9750WSC is designed for charging single-cell lithium-ion or lithium-polymer batteries from 3.3V to 4.2V with up to 2A of charging current. It implements a constant current/constant voltage/constant current algorithm and supports an input voltage range from 5V to 12V. It also employs an overvoltage protection circuit, short-circuit protection circuit, reverse current protection circuit, and over-temperature protection circuit to ensure the safety of the battery pack.

At the heart of the RT9750WSC is the Charging Monitor Unit, which provides precise control and monitoring of the charging process. It monitors the battery voltage and current during charging, ensuring that the battery is charged accurately and to a predetermined voltage. It also trips the overvoltage protection, short-circuit protection, reverse current protection, and over-temperature protection circuits when needed, and provides dynamic current limiting protection to ensure the safety of the system.

The RT9750WSC also features a vast array of communication interface options, including I2C, I2S, SDIO, and SPI, which can be used to communicate with the charger and its associated ICs. It also supports a programmable current limit and has programmable charging profiles for different types of batteries. It also integrates a system start-up function, allowing it to be connected directly to a battery pack without the need for a separate circuit.

In addition to its advanced management features, the RT9750WSC is also extremely efficient, consuming only 7mW during no-load conditions and less than 18mW in full load conditions. It also supports a range of operating temperatures from -40°C to +85°C, making it suitable for a variety of applications. Finally, it comes in a compact, 4.2 mm x 3.2 mm DFN package, making it suitable for space-constrained designs.

In summary, the RT9750WSC is the perfect solution for single-cell LiPo battery applications. It offers a wide array of features to ensure the safety and reliability of charging, as well as superior efficiency, communication interfaces, and a variety of operating temperatures. With its advanced management features and small form factor, it is the ideal choice for battery-powered applications.
