The BQ2002GSNTR is a battery charger IC from the PMIC (Power ManagementICs) series that is used to power and supervise the charging process of rechargeable batteries. This IC provides a complete solution for multi-cell Lithium-Ion and Lithium-Ion Polymer battery pack assemblies. BQ2002GSNTR ICs are designed for high efficiency and low power loss when charging batteries. They are widely used in laptop computers, portable media players, and cellular phones.

The BQ2002GSNTR has two stages of charging – pre-charging and main charging – to effectively manage the charging process. During pre-charging, the IC applies a low current slowly to the battery to minimize any overcharging. Then during main charging, the IC slowly increases the charge current while monitoring the battery voltage, current and temperature to protect against overcharging and overheating.

The main features of the BQ2002GSNTR include an integrated 32 kHz clock, adjustable charge current, adjustable pre-charge count, adjustable start voltage, adjustable end voltage, battery temperature monitoring, and LED driver. This IC is designed to offer high efficiency and low power loss when charging batteries and it also offers excellent performance in cold temperatures due to on-chip thermal compensation. The IC features an integrated LED driver that allows for automatic LED control during charging which helps to reduce power consumption. The BQ2002GSNTR is available in an 8-pin DIP and an 8-pin QFN package for increased durability.

The BQ2002GSNTR is incredibly versatile as it can be used to charge multiple cell batteries with a variety of chemistries including NiCad, NiMH, Li-Ion, and Li-Ion Polymer. This IC is also easy to use and configure with on-chip control and monitoring functions. The integrated temperature sensor can detect changes in ambient temperature and it can be used to control the charging current to optimize charging time and performance. The BQ2002GSNTR also offers protection against over-voltage, over-current and over-temperature.

Overall, the BQ2002GSNTR is an excellent solution for battery charging applications as it offers high efficiency, low power loss, and robust functionality. The integrated features allow for a more efficient charging process and make this IC ideal for portable electronic applications where saving space and power are essential. With high reliability, excellent performance, and durability, the BQ2002GSNTR will ensure reliable battery charging for a wide range of applications.
