PMIC – Battery chargers have been playing a significant role in the modern electrical system since their invention. Nowadays the need for high-efficiency, low-cost battery charging solutions is ever increasing and this is where BQ2002TSN technology comes in. This article explores the application field and working principle of BQ2002TSN charger.

BQ2002TSN is a fully automated battery-charging IC designed for use in dual-channel Li-ion chemistry battery charging applications. It is distinguished by offering a fast charging solution with safety and flexibility in mind. Unlike other existing battery charging systems, BQ2002TSN has a built-in flow-control feature, which allows it to fast-charge lithium-ion batteries without the risk of overcharging.

The BQ2002TSN is suitable for a wide range of applications, ranging from consumer electronics to automotive battery-charging systems. It is widely used in various consumer electronics such as mobile phones, tablets, cameras, laptops and power banks. It is also used in automotive applications such as hybrid and electric vehicles and charging stations.

BQ2002TSN’s feature-rich design makes it a highly efficient battery charger. Its built-in over-voltage, over-current and thermal protections ensure that the battery is charged safely and securely. It is designed to maintain steady and high-speed charging even when the input voltage is unstable. With its low-power consumption, BQ2002TSN also helps to reduce operating costs and maximize battery life.

BQ2002TSN works on the concept of current monitoring and voltage control. It uses an internal voltage-measuring circuit to monitor the battery voltage. It then adjusts the charging current based on the measured voltage and the desired charge voltage. When the voltage reaches the predetermined maximum level, the charging current is reduced until the desired charge voltage is reached. To make sure the battery does not overcharge, the BQ2002TSN features an active over-voltage protection circuit which will reduce the voltage until it reaches the recommended level for a safe charge.

BQ2002TSN also features dual-mode charging, which allows the user to choose to charge the battery at either a constant current or constant voltage. This feature offers greater flexibility and control over the charging process. Moreover, the charge termination feature stops the charging process when the battery is fully charged, preventing overcharging and prolonging battery life.

In conclusion, BQ2002TSN is a highly efficient battery-charger that offers safety and flexibility to its users. Its feature-rich design and dual-mode charging capability make it ideal for a wide range of applications, from consumer electronics to automotive batteries. Its active over-voltage protection and charge termination features help to ensure safe charging and to prolong battery life.
