The BQ24002PWPG4 is a type of Battery Chargers that are part of the PMIC (Power Management Integrated Circuit) family. This regulated multiple-output charging solution is intended for use in portable applications, where high levels of efficiency and quality performance can be expected. It offers low-cost and minimum external components solutions for multiple output battery charging solutions. As a PMIC-type controller, the BQ24002PWPG4 also provides a programmable and robust charging controller for up to four differently sized batteries, and includes features such as a wide input voltage range, boosting, low Rds(on) current source and sink, programmable input current and output current, and thermal shut down protection.
The BQ24002PWPG4 offers low-cost and minimum external components solutions for multiple output battery charging solutions. It also provides a programmable, rugged and reliable charging controller for up to four differently sized batteries. With a wide input voltage range, boosting, low Rds(on) current source and sink, programmable input current and output current, and thermal shut down protection, the BQ24002PWPG4 is an efficient and reliable choice when it comes to battery charging.
The BQ24002PWPG4\'s charging circuit is composed of an efficient Step-Down converter with peak current mode control and voltage feedforward, Automatic Power Source Selection (ACPS), and an integrated N-channel MOSFET. The Step-Down converter provides a constant output voltage, and its peak current mode control provides high step-down efficiency. The integrated charger includes various features to help ensure a safe and efficient charging process, such as protection from reverse current flow, over-voltage and over-temperature protection.
The Automatic Power Source Selection that is included in the BQ24002PWPG4 allows for a choice between AC or USB power, depending on the current source that is available. This feature enables the user to select the power source for the best possible efficiency, and to ensure that the charger does not overheat or suffer from losses due to an insufficient supply.The integrated N-channel MOSFET in the BQ24002PWPG4 provides low on-resistance, as well as allowing for a fast switch-on and off. The MOSFET remains off until the power source is detected, at which time it is immediately turned on. This helps to conserve energy and to prevent overloading and short circuits.The BQ24002PWPG4 also has a set of programmable input current and output current settings. The user can adjust the charge current level, as well as the output current level, so as to meet the needs of the battery. This helps to ensure that the battery is charged properly and that the power output is optimized for the best possible performance.
The BQ24002PWPG4 also has built-in thermal shutdown protection, which helps prevent any possible damage to the device due to an over-heating of the charging circuit. The thermal shutdown kicks in when the temperature exceeds the predetermined threshold, and automatically shuts off the power supply to avoid damage to the device.
In conclusion, the BQ24002PWPG4 is a versatile, low-cost and reliable charging solution for up to four differently sized batteries. With its various features, such as wide input voltage range, boosting, low Rds(on) current source and sink, programmable input current and output current, and thermal shut down protection, the BQ24002PWPG4 can be counted on to provide a safe and efficient battery charging solution for any application.
